How long did we give Gus to consider leaving PEC Zwolle ? How long for Saka or Milan ? Remember, it's not even that he's leaving his home area, his decision is to move further away from Romania if he comes here.
We are not Liverpool or Manchester United where players will agree to move the moment a potential transfer is raised. If this lad thinks he can get a regular game in Liege's first team and maybe even into the Europa League squad, he isn't going to want to jump straight into a batshit crazy English Championship squad with no ideas what will happen. I doubt a lot of mid-Prem players would want to drop to our level as well so he has some considerations to make.
We may be in a rush to get a signature in the next 2 weeks, he's considering his next 3, 4 or 5 years.
