Silva 32 going on to 33, Gundogan is even more injury prone, than Thiago and also...different kind of player. They have KDB, period.
Pep coached him in Bayern. If he was as good as you say, he would be in the City as we speak.
If he is available for 40-50 mil i m all for it. But anything higher than that would most likely be a bad bussines.
This is true at the end of the day.
If Thiago is THAT good, all teams would have been after him.
But not even his father, Pep, is after him.
There is always a reason.
Having 3 similar, weaker players in a team, is not one of them.
That is like saying: we don't need Verrati because we have Gomes and Denis on his position. Ok, these two are very poor, but the point stands.
Pep doesn't want him after Bayern years. That is a huge warning sign.
