Apart from being very profitable for the club, Gundogan himself also has nothing to lose by leaving for a big club like Barcelona because he didn't go to a bad club. Gundogan can still have a very good career at Barcelona at a level that is not much different from before so that Barcelona will also benefit enough to have Gundogan next season. Because that will make Barcelona stronger to compete with other English teams when they meet in the UCL competition.
I don't think so. he loses more chance to win UCL next season. I think that barcelona will not able to perform the same like manchester city did next season. Barcelona is bad club when it came to the european competition.
Do you remember when barcelona was losing in UCL last season and it's also losing in UEL too? That proves that if barcelona is not a good team for european competition.
gundogan was making bad mistake. Silva shall not follow him.
