The rumors have been on for sometime now, with the season now over and City have three more trophies added into their trophy cabinet, the players can now make a decision on their future, so that the club can make adequate provision for replacements. Gundogan and Bernado Silva are very important players for City, but i'm pretty sure that if they leave, Pep would be able to identify who he wants as replacements, and the club would try to get them. Kovacic is almost certain to join City this summer and there would be more reinforcements coming in, City wouldn't struggle next season even if they lose these two players.
