The season hasn't started yet and he may have started making statements to the press early. I hope it's not the same as when he was at Manchester United, where he started with losses in friendlies and then came his interviews in which he complained about players and the relationship with the players became terrible, then he made terrible signings.
Now at Leverkusen, he already had a defeat in which he conceded 5 goals in the friendly match. In 5 days, he will have another friendly match against Bochum, who were recently relegated from the Bundesliga. If he loses, it will be terrible for him.
Getting flogged by Flamengo U21 a few days ago was just a prelude of what is to come. Xhaka knows Leverkusen is finished with ETH at the club, and that's why he wants out before it's too late. Another thing is that he's not fighting to move to a bigger club, as most players would do. He's fighting to go to Sunderland, which Leverkusen is obviously bigger than. That tells me he's desperate about leaving and does not want to stick around when the ship starts sinking.
I have been saying this that Eric is not a good manager right from he's time at Manchester United but no one believes me, Manny were saying he needed time while some were saying Manchester United doesn't have the kind of players needed and he went on to kill the team poisoned the mind of players, disrespect players saying he don't take nonsense from players while he was the nonsense, now I'm being vindicated now he's joined Bayern Leverkusen, Eric was just fortunate in his time at Ajax, he doesn't have coaching sense rather ego and pride towards players, imagine a player like cr7 and David de gea he let them all down and brought in onana and hojlund, two Manchester United biggest mistakes.
