Blackburn Rovers striker Yakubu believes that he has "nothing to prove" after scoring two goals on his debut for the club.

The deadline day signing from Everton claimed a brace as Rovers defeated Arsenal 4-3 at Ewood Park on Saturday afternoon to ease some of the pressure on manager Steve Kean.

After the match the Nigerian international told the club's official website that he has always had belief in his ability and that he was delighted with the three points.

"I always believe I can score whatever team I play for, so to have the opportunity to play for Blackburn is a great feeling," said the 28-year-old.

"To be scoring again back in the Premier League is great and for me to score two against Arsenal and to get a win is a great feeling.

"I have nothing to prove to anyone — I know I can score."

Yakubu spent a part of last season on loan at Leicester City in the Championship.
