Barcelona forward Pedro has admitted that it will be "tough" to come away from Glasgow with three points against Celtic on Wednesday night.

Barca needed a late Jordi Alba goal to beat Celtic at the Nou Camp a fortnight ago and Pedro is wary of the threat of the Scottish side, especially because they "need the points".

"It will not be easy to win in Glasgow, but we are very prepared for the match, especially because Celtic need the points," Sky Sports News quotes Pedro as saying.

"It was a hard-fought victory at the Nou Camp but in the end, the best team got the three points.

"If we get the win in Glasgow we have practically qualified to the next round and this is a big motivation for us."

Celtic are currently second in Group G on four points, five behind Barcelona.
