A pretty good offer from Man United's price of 42 million euros. I read that Valencia only made an offer of 25 million euros. Maybe it's a good decision for Man United to release him immediately. Unless Ten Hag wants to use Greenwood's services again. Greenwood's condition is not bad, he just needs to readjust and grow his confidence to improve even more. I'm sure he's learned and realized, so he's ready to work hard again. He is still young, he is still very capable of developing better.
But, the Manchester United's fans not welcome with him, this might the reason why Greenwood not want to play for Manchester United and choose the management to include him on transfer window. He's not that bad, he's still young and it wasn't injury that make his career decline, so I believe he can still improve. At least he still has a chance to play in top teams in Serie A.
