Jose Mourinho v Arsene Wenger focus
Chelsea manager Jose Mourinho and Arsenal boss Arsene Wenger went head-to-head again at Stamford Bridge on Saturday.
Here, Press Association Sport's Jim van Wijk looks at how the men in the dugout matched up.
Mourinho was waiting in the technical area for Wenger to emerge from the tunnel, and immediately offered his hand, which the French coach was quick to accept, if perhaps appearing to do somewhat begrudgingly before heading swiftly off to the away dugout.
While Wenger spent the early part of the match firmly in his seat conversing with assistant Steve Bould, Mourinho prowled the touchline, encouraging the home side into every challenge and counter attack. The Portuguese coach, though, was less than impressed when Chelsea's first-half penalty shout following a wrestle between Eden Hazard and Gabriel was turned away by referee Mike Dean.
It was then Wenger's turn to shake his head following a red card for Arsenal's Brazil centre-back - and he gave the officials a stone-faced glare as they walked off at half-time.
The second half saw both men back in their seats, before Mourinho revelled in Chelsea's goal celebrations and Wenger again scowled in disbelief when referee Mike Dean showed captain Santi Cazorla a second yellow card, leaving his side to finish the match with only nine men.
Chelsea again started with captain John Terry on the bench, as Kurt Zouma was deployed at centre-back alongside Gary Cahill. Wenger opted to start with the in-form Theo Walcott at the front of the attack, the England forward's pace a potent weapon on the counter.
Following a slow start for the home side, Mourinho moved playmaker Hazard into a more central role to give support for Pedro.
Chelsea's persistence following the red card paid off when Cesc Fabregas delivered a fine free-kick for Zouma to head home on 52 minutes - but Wenger would have been left than impressed by the lack of a challenge from one of his players as the ball floated into the six-yard box.
Wenger tried to change things by bringing on Alex Oxlade-Chamberlain and Olivier Giroud, but there was little time for them to bed in before another dismissal shifted the balance once again.
Wenger had to make a change at half-time to bring Calum Chambers into the defence.
Mourinho was able to opt for a positive second half switch when he sent on Ramires for Oscar.
With 15 minutes left and time running out for the 10-men to conjure an equaliser, Wenger turned to Giroud and Oxlade-Chamblerain - but following another red card, for Cazorla, it was a case of damage limitation.
The decisions of the referee rather than in-match changes by either manager settled this contest, but that will not matter to Mourinho.
