The Hatem of say 5 years ago may not have ran through a wall for him; but the Hatem of today likely would. The player today is far different and seems much more thankful he's still playing brilliantly.
I bet Townsend and Lascelles are probably making the strongest cases for being key starters next season and likely Sissoko too (who I think Rafa sees massive potential in). The rest are all up in the air IMO.
