Yeah, but your opinion is based on...nothing, and that deserves to be pointed out.
Italy's window closes the day after ours.
The only other team competing for Alisson's signature was Chelsea.
So every club involved in making this transfer had an early end to the transfer window. Liverpool were not at any disadvantage because of the Premier League transfer window, all that happened is a deal which might have happened on the 20th of August happened a month earlier.
A transfer saga that would have lasted 4 months only lasted 3 - where is the damage?
