The duo have a long-running feud, and it continued on Sunday at Stamford Bridge when the two sides clashed in the Premier League.
Midway through the first half, the two managers squared up to each other, exchanging shoves and pushes. They were eventually separated, but not before making everyone watching the game amused.
It was indeed amusing how Wenger and Mourinho pushed each other, and many former footballers and pundits took to social networking site Twitter to have their say on the matter.
Below is what Leeds United attacker Noel Hunt and former Tottenham Hotspur striker Gary Lineker made of the incident.

Not sure either Wenger or Mourinho would be much good in a scrap, but might be worth viewing.— Gary Lineker (@GaryLineker) October 5, 2014
A punch-up between the 2 managers at halftime would be sensational entertainment. Get 'em gloved up @EddieHearn— Gary Lineker (@GaryLineker) October 5, 2014

Mourinho had the last laugh on Sunday, though, as Chelsea won the match 2-0. Eden Hazard put the Blues ahead in the 27th minute from the penalty spot, and Diego Costa wrapped up the scoring 12 minutes from the full-time whistle.
Chelsea are now five points clear at the top of the Premier League table, while Arsenal a point behind fourth-placed Manchester United in eighth.
