Ghanaian star Anthony Annan has thanked team-mate Michael Essien for recommending him to Chelsea.

The Blues are being linked with a move for the impressive 21-year-old after Essien suggested to his club they should take a close look at Annan.

Annan is currently with Start in Norway, who he joined after a move to Blackburn fell through because he could not get a work permit.

Now Annan is a regular with Ghana and a move to England could be an option, although clubs from France and Germany are interested.

"I'll do whatever I can to make Chelsea stronger. If that means when I see a good player I tell my club, I will do that," said Essien.

Annan was delighted that Essien rates him highly enough to say he could play at Stamford Bridge.

"It is exciting to hear of Chelsea's interest in me. If Michael has recommended me, I am very grateful," he said.

Annan's club Start told skysports.com earlier this week that they had not been contacted by any English clubs, but there was interest from Germany and France.

Caen and Borussia Dortmund are now being linked, although it is thought English scouts are beginning to take a keen interest in the young midfielder.
