Sancho is obviously very talented, but he has failed to show it on a regular basis for a number of years now. Glimpses, yes, but nothing more.
However, two things in my mind that I'm clinging to:
1. The last forward we loaned from Man Utd with a 'problematic' reputation did pretty well for us with a bit of Unai guidance.
2. It's a World Cup year, and he'll be 26 when it rolls around, smack bang in the prime years for a wide forward, so if he's not motivated to really turn it on this season, he never will be.
I'm a bit surprised we've gone in for him (like many), but as always, I trust Unai and his team if they think he can add something to the side that we weren't getting from Bailey.
