He just wouldn't play Europa league. If we don't qualify for the CL, he's not staying.
That's the only silver lining of the season for me to be honest. Assuming Ralf is given some funds and capacity to make decisions, the likes of Ronaldo, Cavani, Pogba, Lingard etc leaving would help us in building a team that Ralf and the new guy will want while clearing up space on the wage front. Obviously, it sounds theoretically better but we have a disbalanced and bloated squad which requires a lot of fine tuning. We can focus on a style of play and sign players according to it rather than have a scattergun approach where we're signing names rather than players who have a set role.
