Manchester United defender Patrice Evra admits the way they've been conceding goals is a concern going into their clash at Chelsea.
The constant switches in personnel are not helping Sir Alex Ferguson's team. But whoever lines up at Stamford Bridge, Evra is adamant there must be an improvement.
"If you concede three goals at home, you can hardly say it has been a good performance from the defenders," he reflected.
"We did well to come back, as we did against Manchester City. But we need to make sure we don't concede three goals on Sunday because then it won't be easy to get back."
United are looking for their first win at Stamford Bridge since 2002, another reason why Evra might not regard the venue as one of his favourite grounds.
In fact, he loves it, which is partly due to the fact that he, personally, has never been in a side that has lost there.
"Apart from the Community Shield, I have never lost against them and I aim to make sure that run continues," he said.
"If there is one game I want to win this season, it is the one at Stamford Bridge. I didn't know it has been so long since our last victory there. It is the right time to end that run."
