Barcelona defender Marcos Alonso admits victory at Osasuna last night was a battle.

Barca won 2-1, despite losing Robert Lewandowski to a red card on 30 minutes. Substitute Gerard Pique was also dismissed at halftime in the final game of his career.

Alonso said: "The game was unfairly uphill for us. We are very happy. We have not given up and at half-time we talked about having chances to win. Three points and the lead (at top of the table).

"I don't want to go into talk, but people will have seen some decisions from home. A little sad that these types of errors still occur.

"I don't know what happened to Piqué. I think he leaves happy with the three points and the farewell the other day.

"A shame but he leaves happy with the three points."
