Martin Keown warns Jose Mourinho after sending off against West Ham

Arsenal legend Martin Keown has warned Jose Mourinho that he cannot keep reacting like he has over the past few days if he has to keep the sanctity of Manchester United alive. The Portuguese manager was sent off against West Ham after he kicked a bottle on the technical area, frustrated by referee John Moss' decision to brandish a yellow card to Paul Pogba.

This is the second time this season that Mourinho has been sent to the stands at home after suffering the same fate against Burnley where the Red Devils succumbed to a 0-0 draw despite having the majority of the chances. Against the Hammers, they went a goal down in the opening two minutes but came back into the same through Zlatan Ibrahimovic, who latched on to a brilliant pass by Paul Pogba and headed home from close range.

The Red Devils pushed and probed all game to find the winner but were faced with an immovable force in the form of goalkeeper Darren Randolph, who had the game of his life and managed to keep the hosts at arm's length. The draw is United's fourth consecutive one at home, which has opened up a 11-point difference at the top and all but ended their hopes of challenging for the title. However, Keown believes that irrespective of how United are playing, Mourinho should keep a lid on himself and keep away from harms way.

"We can only imagine that Mourinho feels that Pogba has been fouled. This is a massive overreaction. It is not like it is a penalty decision. I don't get it. He knows he's going to get sent off. Listen, he's in a massive job and he needs to keep that lid on things. People say "you're a former Arsenal player and you don't want to see Manchester United do well", but we do want to see good football, Keown said, as quoted by the Daily Mail.

"They were unlucky today but the hierarchy will not be happy with the image he is creating around that football club; he is overreacting. It is the second time it has happened and he needs to keep a lid on it," he added.
