Porto midfielder Paulo Assuncao can't guarantee he will be with the Portuguese club next season.

Assuncao is a target for Atletico Madrid and is keen on a move to Spain. He said: "I cannot guarantee that I'm going to continue next season here, you must ask the president."

The midfielder has just over a year left on his current contract and Atletico believe they can land him for a knockdown fee courtesy of a clause in his deal.
