I have heard that if manchester city unwilling to sell him to its competitor. If gundogan will be going to the arsenal and it seems like that rumor was not true. Remember that arsenal became a good team caused by it was getting some players from manchester city in the past. I will support gundogan to go to the barcelona rather than arsenal. Gundogan has not yet decided his future and i think that the rumor about he will be going to the arsenal will not true.
Gundogan may stay or go to the barcelona. I prefer to see him join in barcelona. It will be far better for him.
Man City have a lot to learn from the transfer of Gabriel Jesus. He's a player who is still very good and he was close to winning with Arsenal. Releasing players in one competition is too risky. A sling could be a double-edged sword for Man City. So they shouldn't sell to Arsenal. In addition to Arsenal and Barcelona, I also read that Al Hillal, a Saudi Arabian club, wanted him. At 32 years old, he can still play in the EPL or other leagues for at least 3 more years. Staying at Man City is also good, he can make good history again next season.
