First-half goals from Sergi Roberto and Robert Lewandowski sealed the win that moved the Blaugrana to 59 points, eight ahead of second-placed Real Madrid.
“Scoring twice before the break gave us a comfortable lead that practically sealed the win for us going into the second half,” Xavi told Movistar Plus.
“We had a good and solid first half and I’m satisfied, although we eased off after the break.
“Maybe the team got a little tired but we are happy because we kept our eight-point lead at the top of the standings.”
That fatigue is a looming factor for Xavi’s side who take on Manchester United on Thursday in the second leg of their Europa League playoff tie, having drawn the first leg 2-2 in Barcelona.
“Frenkie de Jong and Robert Lewandowski played more minutes,” Xavi told Marca.
“I think they have been playing a lot of minutes, that’s why I made the changes.
“The other day Pedri was injured and we cant afford more injuries.
“Let’s prepare for Thursday’s game from tomorrow and see how tired they are.”
