Robert Lewandowski has proven to be a worthy striker for the blaugrana, and he has no trouble becoming acquainted with new players. These new players will improve the club's performance and their own for the coming season. Xavi has a bright vision for success at Camp Nou, and he's not far from fulfilling it. It is now time for Xavi Hernandez to establish a club where he will not be disappointed to confront his opponents in the Champions League next season, and to strengthen vulnerabilities in preparation for the future difficulties. IIkay Gundogan is a fantastic signing who will make significant contributions to the team.
Lewandowski is a prolific striker at Barcelona as well. However we haven't been able to see enough level of contribution by him in big matches of the Champions League. It was like he was a more different striker than his La Liga performance. He wasn't having issues against weaker opponents in the Champions League. But he was a failure when it comes to facing teams like Bayern Munich in the group stage. He will need to concentrate more on that kind of matches from now on as those ones are critical for making it to beyond the group stage.
Barcelona actually need to try new things in the Champions League from now on. The strategies don't work good enough as we have seen for two seasons here.
