"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."
