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.
Since announcing Erik Ten Hag as headcoach, we've seen quite alot happening and I must confess, there's very sign of weakness for Bayer Leverkusen. On a second thought, Defeats is not a bad thing rather its seen as one a little bit of setback inother to boost the morale of the team to bounce back. Bayer Leverkusen doesn't seem ready for this current season based on their current form. Who's Flamengo that Leverkusen would lose to? Common brother even though it's a friendly clash, I don't expect such huge goal margin coming from Flamengo. However let's be positive and trust the new administration of Erik Ten Hag.
I don't think Ten Hag can coach Bayer Leverkusen well, I really don't know what made Bayer Leverkusen to buy him after seeing the way he coached Manchester United, I thought the reason clubs go for a coach is because of the good impact they lift in there form club, I'm not saying Ten Hag was totally bad when he was in Manchester United at least he helped them to lift a trophy but in there league which is the English premier league Manchester United was very down, to be honest he didn't coach Manchester United well so I don't see him coaching Bayer Leverkusen well too.
Bayer Leverkusen losing to Flamengo is a good sign that they will not perform well this coming season, I'm very sure Bayer Leverkusen will sack ten Hag before next season runs down, except he will improve the team but I don't see that happening Bayer Leverkusen made a very big mistake, well like you said Obari let's be positive and trust the new administration of Erik Ten Hag.
Good luck to Bayer Leverkusen and to Ten Hag.
