The Blues face top-four chasing Southampton at Stamford Bridge on Sunday after the west London side crashed out of Europe’s premier club competition on away goals following a 2-2 draw with Paris Saint-Germain on Wednesday night.
It is more difficult to start the season with the same points as everybody then to play now with an advantage
Chelsea have five point lead at the top of the table and have played a game less than their closest rivals Manchester City, and Mourinho is confident his Blues players can get the job done in the final 11 games.
Speaking at his pre-match media conference at Cobham on Friday afternoon, Mourinho said: “Why are you so pessimistic in life? It is more difficult to succeed.
“You have to be optimistic. Maybe you are a guy with a great potential and you don’t move on because you are so pessimistic. Be optimistic. Be positive. Believe in yourself. We want to win against Southampton.
“We have an advantage of five points and a match in hand. We cannot promise that we will win every game but we will try. We are optimists. You look very pessimistic. You have to enjoy life in a different way.”
Mourinho added that he feels more relaxed with Chelsea’s current position in the title race than at the start of the campaign when the Blues didn’t have a points advantage.
“They’ll cope with the pressure of playing Southampton,” Mourinho added. “We are having key games since the start of the season.
“It is more difficult to start the season with the same points as everybody then to play now with an advantage. We have five points more than Manchester City and nine points more than Arsenal. In this moment, it is easier.”
Chelsea are unbeaten at Stamford Bridge in the Premier League this season ahead of their clash against Ronald Koeman’s side on Sunday.
