Manchester United defender Patrice Evra was not pleased with their performance in the 3-1 home victory over Chelsea in the Premier League on Sunday.
Goals from Chris Smalling, Nani and Wayne Rooney at Old Trafford saw United maintain their perfect start to the Premier League season and go clear at the top with 15 points from five matches.
However, Evra is not happy with the way they played against Andre Villas-Boas' side, warning his team-mates against a similar performance as the season progresses.
"Maybe I am being hard on myself but it is the first time we didn't control the game," said the France international left-back.
"We have five wins. Yes, it is a good start but I always want more. I hope we control the next game against Stoke.
"We shouldn't rush things. That is why we gave the ball away too easily. That is why I am not so happy. We won a big game. We have scored three times against Chelsea. There are a lot of positive things.
"But when they scored the early goal in the second half I thought 'we have to be strong to make sure Chelsea back and maybe even win 4-3'. If we want to win the league we will have to perform better than this."
Teenage defender Phil Jones had a strong game against the Blues in front of the United supporters, playing an important role in building up attacks from the back.
Midfielder Michael Carrick is pleased with the performance of Jones and the other young United players so far this campaign and enthused: "These young lads are enjoying themselves.
"They have got an opportunity they possibly didn't think would come so soon. Now they have the chance, they want to make the most of it.
"When you are so young, you have never really had any setbacks. You just play the game freely and with enthusiasm and enjoy it. They are certainly doing that at the moment."
