Arsene Wenger tells Jose Mourinho not to sit by him at coaches conference in Switzerland

Arsenal manager Arsene Wenger told Jose Mourinho not to sit next to him during a recent coaches conference held in Switzerland some days ago.

Arsene Wenger told coach Mourinho that it is not possible for him to sit next to him, after Mourinho showed up late for Sir Alex Ferguson speech. The only empty seat left for Mourinho to sit at that moment  was  the only seat next to  Arsene Wenger, and Wenger quickly told Mourinho not to sit beside him.

Who's responsible for starting this feud is certainly up for debate, as Wenger has done his fair share of moralizing about Arsenal playing the right way and Mourinho's teams playing anti-football. But it's indisputable that the recent unprompted pot-shots have come from Mourinho, who has called Wenger a "specialist in failure" and took shots at Arsenal in his first press conference as Manchester United manager.
Mourinho vs. Pep is the big on-pitch rivalry in the Premier League right now, while Mourinho vs. Wenger will always be the league's greatest off-pitch rivalry.
