Arsenal manager Arsene Wenger and Chelsea boss Jose Mourinho could face a two-game touchline ban after a heated confrontation during the first half of the Premier League game between the two sides at Stamford Bridge.

Wenger appeared to push Mourinho before the pair exchanged expletives following Gary Cahill's challenge on Alexis Sanchez during the first half of the Blues' 2-0 win on Sunday. Neither manager shook hands at the final whistle and could be reprimanded for their actions.

The Football Association are likely to deem the incident a breach of regulations regarding technical area occupants. Should Wenger and Mourinho admit a charge under rule E3 both managers could face an £8,000 fine and a one-match touchline ban.

However, should either individual deny the charge they face a fine of up to £12,000 and a two-game ban from the technical area. The FA have until 5pm on Tuesday to confirm charges against the Arsenal and Chelsea pair.

One-game bans would see Wenger absent from the touchline for the visit of Hull City and Mourinho banned from the dugout for the trip to Crystal Palace both on 18 October.

But ahead of an announcement by The FA, Wenger has indicated he could challenge any ruling after stating he didn't regret the altercation as he attempted to check on the injury sustained to Sanchez.

"What is there to regret after that? I wanted to go from A to B and somebody confronted me in between without any sign of welcome," he said in his post-match press conference. "B was Alexis, to see how badly he was injured.

"I trust that you will teach me all the moral lessons over the next three weeks and I can accept that. But I've been in the game long enough to give it the right weight.

"I can try to push you and when [I do] you will see what my [pushes are really like]. It was a little one."

Mourinho though appears less likely to challenge any FA charge after admitting to confronting the Arsenal manger, who he perceived was attempting to have Cahill sent off after just 20 minutes.

"It becomes heated because it's a big game, big clubs, big rivals, an important match for both teams," the Chelsea boss said.

"These conditions make a game of emotions. After that, there are two technical areas. One for me, one for him. He was coming into my technical area and not for the right reasons, to give some technical instructions. He was coming to push the referee for a red card, and I didn't like that."
