Barcelona defender Gerard Pique has claimed that his team have an obligation to play a certain way and not just purely focus on recording positive results.

The Catalan outfit are currently on a 37-game unbeaten run in all competitions and have been tipped to make it back-to-back trebles this season.

Pique, who has been an ever-present in Luis Enrique's first-choice XI this term, has insisted that playing for Barcelona is not just about winning, "but playing well".

"There is a lot of work and three very hard months ahead. We'll try to win it all again because it is up to us. We will give everything to do it in the best possible way," Pique told UEFA.com.

"Winning is a must here, and not just winning, but playing well. We have a once-in-a-lifetime generation of incredibly talented players and we have to maximise it."

Barcelona will attempt to book their spot in the quarter-finals of the Champions League when they welcome Arsenal for the second leg of their last-16 clash on Wednesday.
