Defender Jordi Alba says Barcelona need to make some changes after dropping seven points in six days.
Barça were held to a 1-1 draw by Athletic Bilbao on Saturday after losing to Leganes in midweek and being held by Girona last weekend.
"That’s three games without winning," Alba told reporters. "It’s clear that we have to make changes to try and get three points.
"We have to look at a lot of things. But the team tried, we just lacked a little luck. We got into the box a lot and the ball didn’t want to go in.
"There’s no need for alarms. I think it’s clear we’re not satisfied with the results and that we can all give more. The season is just getting started. Despite the three slip-ups, we’re still up there and there’s a long way to go. We all have to give a lot more."
Lionel Messi was on the bench, rested with Tottenham in mind, but came on to set up the equaliser for Munir having previously hit the post and seen a free kick cleared off the line.
"Obviously Leo gives us a plus," Alba added. "When he’s on the pitch we create more and we’re much better. I think that we have a squad to get results without him. But the reality is that we’re much better with him and we want him to play all the time."
