Chelsea boss Avram Grant has praised his 'patient' Blues side for the way they waited until the perfect moment to finish off Birmingham today in the Premiership. Chelsea substitute Claudio Pizarro scored the winner in the 79th minute.

"Although the goal came late, we had the majority of the possession except for the 10 minutes at the end of the first half," said Grant.

"We didn't create so many chances but still had two or three opportunities before we broke through.

"Birmingham played with a lot of spirit and determination and fought very well but we deserved the win.

"We were aware that Birmingham had picked up points against Liverpool and Arsenal this season and it was very important to win here. They had only lost 1-0 at Manchester United.

"It is very difficult to play against them. They know how to defend and make good counterattacks so you need to be patient against them.

"We were patient because in these games you don't get many chances - especially against them at their place."

Grant was pleased to see Pizarro score his first league goal since netting in the 3-2 win over Birmingham on the opening day of the campaign.

"It was one of his best games. He did a very good job for us and deserved the goal. It was well taken," added Grant.
