Tensions ran high yesterday as fans were entertained when Arsenal boss Arsene Wenger and Chelsea manager Jose Mourinho squared up on the touchline.
Some pushing and shoving took place as Wenger insisted he was confronted by Mourinho as he started to move towards Alexis Sanchez to check if his Chilean star was injured after a challenge from a Chelsea player.
Mourinho and Wenger have history and things threatened to reach boiling point, giving the fourth official plenty to sweat over as the match unfolded, with the Blues eventually winning 2-0.
Last season Mourinho branded Wenger a ‘specialist in failure’ for not winning a trophy for nine years before the club’s FA Cup triumph.
Arsenal were also on the receiving end of one of their worst ever defeats to Chelsea last season when they won 6-0 at Stamford Bridge with Andre Marriner infamously sending off Kieran Gibbs thinking he was Alex Oxlade-Chamberlain.
Here are some of the best mock-up pictures of the incident which appeared on Twitter after the square up.
