Chelsea captain John Terry has said to Arsenal, Manchester City and Manchester United that they allow too many goals in to challenge the Blues in the Premier League title race.
Jose Mourinho`s side are five points clear of second-placed Manchester City after a 2-0 victory over the Gunners at Stamford Bridge on Sunday.
And the former England captain has insists that Chelsea have found perfect the right balance between attack and defence.
Terry told the Daily Mirror: “You’re just hoping when you’re at the top and have a five point cushion – and six, seven, eight on certain teams – a couple of them slip up again and that increases to eight or nine.
“If that happens, it’s a lot of points to give up early on. All we can do is keep winning and wait for those teams to slip up.
“You have to look at everyone, Man City, Man United, Arsenal… and they are all conceding goals and that’s because of the quality in the League – it is getting better, it’s as simple as that.
“We are more attacking this year, but defensively we are now very solid. Everyone was questioning our defence early on in the season, but it’s going to happen.
“There are so many good teams and individuals in the league, we are going to concede goals. The important thing going forward is we have goals in us. As long as we’re not conceding too many.”
