Chelsea head coach Carlo Ancelotti has warned his side that they need to improve if they are to have any chance of winning the Champions League this season.

Ancelotti was speaking after an unconvincing 2-1 home win over Slovaks MSK Zilina which ensured that the Blues will finish top of their group.

The Italian said:"It was a difficult game because we didn't start the game well and were 1-0 down.

"We had a good reaction in the second half, with more intensity and good play and plenty of opportunities to score. The second half was very good.

"But if we play like we did in the first half, it's impossible to win the Champions League. If we play like we did in the second, then we'll have a chance.

"I was disappointed because this was an important game and an important moment. We wanted to win and finish first in the group.

"But we didn't play in that first half. We had no intensity or tempo. We changed things immediately in that second half and our behaviour changed.

"It was important to win and move on quickly, to look at the performance in the second half.

"Also, for the young players, it was a good experience. They played well generally and put in good performances for the team."Subscribe to Football FanCast News Headlines by Email
