Bojan Krkic has called Barcelona 'unstoppable' as his Milan side prepare to face the Blaugrana in the last 16 of the Champions League.

The Italian giants have been drawn against Tito Vilanova's side in the first knockout round of the tournament, and the Camp Nou graduate has admitted that it will be tough for his team to reach the quarter-finals.

“The tie will be very complicated,” he told reporters after Catalunya's friendly match with Nigeria last night.

“We know we are playing against the best club side in the world, but we also know that we can cause problems.

“We have some good players and we will try to be in the tie for as long as possible.

“Barcelona though, are unstoppable. They keep creating players that know the philosophy.”

He also commented on his future, and rumours that a return to Barca is possible come the end of the season.

“In football you never know what might happen. The situation is not easy because I have two or three options.

“But for the moment I want to focus on Milan.”
