He more or less single handedly got them promoted last season and now he's more or less saved them from going back down.
Quality player and definitely needs to move if he wants to make the EURO's squad as well as have a decent career in general. Problem is he's likely going to be in a similar situation as Zaha at Palace. Signed a new deal and whilst they're in the Premier League, his value will put off too many sides as Villa won't wanna lose him, they know they'll drop without him regardless of how much they could make.
Missing out on him in 18/19 still annoys me. I'm never gonna let that drop lol...
...Especially as it's meant enduring two seasons of watching Captain Crab in the meantime
