Jose Mourinho takes swipe at 'unethical' Jurgen Klopp and Arsene Wenger

Liverpool manager Klopp said of the proposed £100 million transfer fee for Paul Pogba: “The day that this is football, I’m not in a job anymore.”

According to Wenger, the fee involved in the biggest transfer in history is “completely crazy.”

But speaking ahead of Sunday’s Community Shield, Mourinho bristled at the criticism from his rivals.

"I don’t like to speak about other clubs or players from other clubs, other managers they like to do that and speak about my club and my players,” he said. “I’m very pragmatic on this. The only thing that matters for me is what happens in my house not my neighbours.

“I already heard two of my colleagues from other Premier League clubs and I have to confess I don’t like it. It’s not ethical.

“When others do that nobody says anything I don’t speak about the others, they can do what they want. We made decisions. We brought four players, not 10, who are Man United level and can really improve the squad.

“The others, it’s their problem they can do what they want.”

United take on Leicester City at Wembley hoping to pick up the first silverware of the season.

But Mourinho says he is still in the process of deprogramming his players after spending two years under Louis van Gaal.

“My teams are different than Mr Van Gaal’s,” he said. “It’s a difficult situation to change the dynamics - it would be easier for me to have 20 new players and start from zero. After two years of work, there are things in their brains that are automatic.

“That’s difficult to change, but we are working hard and the players are giving everything to adapt. Step by step, my team is going to be my team.”
