Jose Mourinho has been appointed as Manchester United's new manager and attentions are already turning to the mouth-watering Premier League season ahead.
Mourinho will renew his old rivalry with Pep Guardiola across Manchester, and he will also come up against Arsene Wenger at Arsenal and Claudio Ranieri at Leicester.
Liverpool's Juergen Klopp and Tottenham's Mauricio Pochettino will also hope to challenge at the top of the table, and Mourinho will face his Chelsea successor Antonio Conte too. Here are his head-to-head records against these top managers:
Mourinho v Guardiola (Played 16, won 3, drew 6, lost 7)
Mourinho's bitter rivalry with Guardiola stretches back to his days at Inter Milan, where he famously triumphed over Guardiola's Barcelona in the 2010 Champions League semi-final.
The following season saw the Portuguese chalk up another victory over Guardiola in the Copa del Rey final with Real Madrid, though he also experienced a galling 5-0 La Liga defeat at the Nou Camp.
Mourinho v Wenger (Played 13, won 7, drew 6, lost 0)
The Portuguese will relish another opportunity to face Arsene Wenger. The pair have been embroiled in numerous wars of words since Mourinho's arrival at Chelsea in 2004.
On the pitch though, Mourinho has dominated the Frenchman. He is yet to taste defeat in 13 competitive meetings with Wenger, and his tally of seven victories included a 6-0 thrashing at Stamford Bridge in Wenger's 1,000th game in charge of the Gunners.
Mourinho v Klopp (Played 5, won 1, drew 1, lost 3)
Mourinho's Real Madrid took on Klopp's Borussia Dortmund four times in the Champions League in the 2012-13 season. The German came out on top, winning their group and then eliminating Real in the semi-finals thanks to a four-goal blitz from Robert Lewandowski.
The pair have met once since Klopp's arrival in the Premier League, and it ended in more disappointment for Mourinho as Liverpool beat Chelsea 3-1 last October.
Mourinho v Pochettino (Played 10, won 8, drew 1, lost 1)
Mourinho faced Pochettino's Espanyol six times when he was at Real Madrid between 2010 and 2013, winning on four occasions and drawing twice.
They went head to head four times after moving to Chelsea and Tottenham respectively. The Blues won 3-0 in the first meeting and beat Spurs in last year's League Cup final, but also suffered a 5-3 loss at White Hart Lane in the Premier League.
Mourinho v Ranieri (Played 6, won 2, drew 2, lost 2)
Mourinho replaced Ranieri at Chelsea in 2004 but it was not until the 2008-09 season that they went head to head for the first time. That year, Mourinho's Inter won and drew against Ranieri's Juventus on their way to the Serie A title.
Five years later, however, Ranieri got his own back, as his Leicester side clinched a 2-1 win over Chelsea last December. It turned out to be Mourinho's last game in charge of the Blues.
Mourinho v Conte (Played once, drew once)
It was December 2009 and Mourinho's Inter travelled to Conte's Atalanta for a Serie A encounter that ended 1-1. Conte's brief stay at Atalanta ended just a few weeks later, and they have not faced each other since.
