Guilherme Siqueira has admitted that he is 'unsure' where he will play his football next season.

The defender is currently contracted to Spanish outfit Granada, but spent last season on loan at Benfica, who won a domestic treble.

Atletico Madrid and Real Madrid have both been linked with moves, but the 28-year-old has offered no indication as to his future destination.

"At the moment, my future is uncertain," Inside Spanish Football quotes Siqueira as saying.

"I'm willing to negotiate and stay at Benfica, but I'm also waiting for other offers to appear."

Siqueira started his professional career at Udinese.
