But well, we always try to find ways to improve. I think there are very positive things, and also others to improve. We know that in Europe there are certain things we have to keep an eye on,” he told Cadena SER.“For example, their first chance went in. We need to improve in that area, and they could have scored a second. So we have to learn, maybe try to attack a little more slowly, because if you lose possession, they counter-attack quickly.“These are matches where you have to hold back a little more. But, well, once again the team has shown great character. In the second half, when the goals come, it obviously allows you to enjoy it a bit more. We know it won’t always be like this, and that especially in the Champions League, the matches will be very difficult.“We have to be prepared for all kinds of scenarios, when we score, when we don’t score, and the message is clear: perhaps those ten somewhat crazy minutes we experienced when we conceded the goal, well, to have a little more composure, and that’s a bit of a lesson for today.”Barcelona will face defending champions PSG next in the Champions League; before that it’s a trip to Real Betis in La Liga.
