Arsenal are on red alert after Niko Kranjcar admitted he may leave Portsmouth in the summer.

"I've got my contract for another year-and-a-half and I'm happy to see it out. But at the end of the day if I don't sign a new one the club will probably try to sell me in the summer," he said. "We've had discussions about a new contract but we've put them on hold until the summer.

"The main thing is to keep Portsmouth in the Premier League and we'll see what it goes on. If a bigger club, if a top-four club, or big clubs from Europe come in and want to get me if the price is right of course I would like to go and play Champions League.

"I do hope and I do believe that my career is going to go upwards from here but I am committed to Portsmouth and I am thankful to Portsmouth. They gave me the first opportunity in European football and that's something I will never forget.

"I always said I would stay in January - and that's what I did. What the summer's going to bring, no-one knows. I've got my contract, I'm not going to walk out on it. If they are going to sell me they are going to sell me, but it's still my decision if I want to go anywhere."
