I really doubt Young will leave, but we're definitely going to have to invest quite heavily in the full back areas in the Summer. Valencia and Darmian will go, and I also think Jones and Rojo should. I can't see us losing more than four defenders in one window, it's too much change at once and it'll be a bit too hard to purchase the kind of quality we need in multiple positions during the Summer. I initially expected us to go with Dalot, Valencia, Young, and Shaw next season, but we're going to have to get a new full back at the minimum. I think we can get through the next season with this, then replace Young in the following Summer.
