Arsene Wenger showed he is seriously not one to be messed with – after shoving Chelsea manager Jose Mourinho during Arsenal’s Premier League clash at Stamford Bridge on Sunday. <br /> <br />The Frenchman demonstrated just how tough he really is after getting incensed following Gary Cahill’s challenge on Alexis Sanchez, which earned the Chelsea defender a yellow card, in the first-half of the game. <br /> <br />The tackle led to Wenger exchanging words with Mourinho on the touchline before the Portuguese tactician responded by telling his Arsenal counterpart to return to his technical area. <br /> <br />Seemingly unafraid to back down, though, Wenger then squared up to Mourinho and pushed the Blues boss away before referee, Martin Atkinson, had to intervene to calm the duo down.
