I think he has gears to go into mate, not even close to reaching his potential yet.
Unless he wants to go,which I seriously doubt- I don't think it's the correct time to sell.
Morelos,Itten,Roofe,Kent even would give us more chance of maximising the value we would get for selling them now than Hagi I'd suggest.
Don't get me wrong,there's some very difficult decisions to be made on that front when bids inevitably come in and I'm glad it's not me having to make them.
Spot on Cav.
The big problem we may have is that need to be self sustaining & not being in control of what offers will come in for our players.
A lot of us have thoughts on who will be the easiest to let go, but to a large extent other clubs will be a big part of that.
Unrelated, but I take it you noticed Ivanusec played for Croatia against Czech Republic ? Still only 22 too.
