When Tom Brady and Wayne Rooney cross paths in Birmingham perhaps the best ice breaker will be the NFL legend reminding the former Manchester United and England star of his thoughts on Super Bowl XLVI in 2012.
'Trying to watch Super Bowl final,' Rooney tweeted. 'How do they call this football. Like watching paint dry. Looking forward to adverts and music.'
There has never been anything quite like two sporting titans joining forces like this, with Rooney penning a three-and-a-half year deal to replace John Eustace as manager.
Both are certified winners, that much is clear.

Tom Brady went on to lift seven Super Bowls, more than any player in the history of the NFL
Rooney, Manchester United's all-time leading goal scorer and until earlier this year England's record scorer, can look up to the boardroom to see a man who won seven Super Bowl rings and is widely considered to be the NFL's all-time greatest player.
'I have spoken to Tom,' Rooney said in his opening press conference. 'He is very ambitious to move this club forward.
'It’s great to have him here, it’s important for the players to see Tom Brady have an involvement. It’s very clear that Tom is fully involved in the club.'
Even off the football pitch they have plenty in common - not least, parenting.
Rooney has four sons with wife Coleen: Kai, Klay, Kit, and Cass. Brady has two sons and a daughter - Jack, Benjamin and Vivian.
Brady, who was famously drafted at pick 199 in the sixth round of the 2000 NFL Draft, separated and divorced from super model Gisele Bundchen in 2022 after 16 years together. He revealed in the summer that he was dating Irina Shayk, the ex of actor Bradley Cooper.
But it is on the field and on the pitch where both men did the majority of their talking.
Brady retired for a second time earlier this year as his sport's greatest.

Just some of Brady's records include the most passing touchdowns, passing completions, passing yards, and wins for a quarterback. He was named Most Valuable Player (MVP) of the league three times and the MVP of the Super Bowl five times - the most of any player.
Brady is also the greatest play-off quarterback in the sport - with the record for most games started, games won, passing touchdowns, passing yards (in both a play-offs and in a single game).
Of course, the most notable among his accolades would be seven Super Bowl titles - six of which came with the New England Patriots, the other arriving with the Tampa Bay Buccaneers. Those seven titles are the most of any player in league history.
One crossover between Rooney and Brady, who don't appear to have met prior to this coming together at Birmingham, is that both have played under the ownership of the Glazer family in their careers.
The Glazers - owners of Manchester United and the Tampa Bay Buccaneers said of Brady in a statement following his retirement: 'Tom's impact on our franchise these past three years has been immense and we are appreciative of the time we had with him here in Tampa Bay.
'He set an exceptional standard that elevated our entire organization to new heights and created some of the most iconic moments in our history.

'Tom's impact will be felt within our community for many years to come and we will forever be grateful for those unforgettable memories that he provided during these final seasons of his legendary career.'
As for Rooney, he arrived at Manchester United as a teenage sensation from Everton - scoring a hat-trick on his Champions League debut for the club against Fenerbahce - before going on to solidify himself as a club legend.
As well as five Premier League titles, Rooney won the UEFA Champions League in 2007-08, the FA Cup, three League Cups, a UEFA Europa League, and scored 253 goals for United in all competitions, making him the club's all-time record scorer.
He is also the third-highest scorer in Premier League history behind Alan Shearer and Harry Kane.
One thing a tandem of Brady, who holds a minority stake in Birmingham City, and Rooney will do is attract players that previously may well have been out of reach.
Take the loan deal for defender Emmanuel Aiwu from Italian side Cremonese. He was attracted to Birmingham's vision following the takeover by Tom Wagner and investment from his business partner former NFL superstar Brady.

And for all Brady's successes, he has a net worth of around £35m, he has a humility and a deference to footballers of yesteryear. That will no doubt follow when he meets Rooney.
Brady paid a visit to Manchester United last year where he was given a warm handshake from Cristiano Ronaldo. Later in 2022 he gleefully met Bayern Munich's players in the tunnel after a game.
At Birmingham the former quarterback won't get that sort of elite level stardom but he did not seem to mind when he was in attendance for their EFL Championship opener at home to Leeds United on August 5, just days after his role with the club was confirmed.
Birmingham won the game 1-0 at St Andrew's thanks to a stoppage-time penalty from striker Lukas Jutkiewicz.
The NFL legend also paid a surprise visit to a local pub ahead of the game against Leeds, before heading to the stadium to watch his team win 1-0.
The seven-time Super Bowl winner notably spoke to the players in the dressing room before the game and it appears his words may have helped them get the win.
After the match he claimed he was 'humbled' but the experience, saying: 'From the moment we walked into The Roost, to the second the penalty hit the back of the net, your energy was humbling and a moment I won’t ever forget.
'Thank you to all the supporters for welcoming us into this family with open arms.'

Rooney, unsurprisingly, is equally as excited about the opportunity that lies ahead.
'I am absolutely delighted to be joining Birmingham City Football Club at such an exciting time. It is very clear that they have a plan and are committed to realising their ambition for the club. We are fully aligned on what is expected,' he said.
'I have been building my managerial career, putting myself in challenging environments, to get me ready for this opportunity.
'It's a project that gives me a sense of purpose and I can't wait to get started.'
They may not see eye to eye on the excitement of a Super Bowl - even if Rooney was snapped in the stands at the most recent instalment back in February - but Brady is unlikely to mind.
With 17 major trophies and titles between them, Rooney and Brady have the chance to sprinkle some of their sporting excellence on the Midlands to restore Birmingham to the top flight for the first time since 2011.
