Rangers are L1/L2 standard. He'd be an absolute superstar for them and probably get sold back to a Prem club for around 20 mill where he'd fail miserably... sell on clause needed.
Well, Everton are not a team we need to worry about. So looking further down, if a club around us get someone in and he bangs in 5 before the window slams shut, we will wonder how they managed it and we didn't.
