I haven't heard anything about Xavi after he officially parted ways with Barcelona at the end of this season.
Barcelona has even signed Hansi Flick officially my friend, you missed a lot then.

Here is the source for you which is Barcelona's official website:

Yeah I have also heard about Manchester United's decision on Erik ten Hag's future. It is good to hear for me honestly that he stays. But now it is time for them to have this transfer window as effective as possible. This squad isn't strong enough to play for the Premier League title. A team like Manchester United always aims the top so the transfers should be made according to that. They aren't broke, they have money. They just need to use it more efficiently.
