Barcelona coach Xavi admits they need to buy this summer.
Despite winning the LaLiga title, Xavi says his squad lacks depth.
He said after a final day defeat at Celta Vigo, "I think we have had a great, remarkable season.
"We are aware that we have to reinforce ourselves to compete because Bara is required to, especially in Europe. We have to be competitive, we need two players per position.
"We have taken advantage of the squad. The definitive step is to reinforce ourselves well, to compete for all the titles. We must take one more step to win the Champions League."
