Speaking at Friday???s pre-match press conference he said: “We have 11 matches to play in the Premier League.
???And with the new criteria in place for next season, we have to be the champions to be head of group in the Champions League next year.???
And what has he said to the squad following their loss in midweek: “I reflect with the players not with you.
“I had a meeting with the players, I’m working for the future and I don’t have to share that with you.
“I don’t want to go back. I want to go forward. I think they will cope with the pressure of playing Southampton.”
As for the remainder of the domestic season, Mourinho said: “We cannot promise to win every game, we cannot promise that we will win the Premier League, but we are optimistic.
“You have to be optimistic to succeed. Be optimistic. Believe in yourself.???
