It's difficult to call, with 3 new attackers available and Fletcher closer to fitness, there are a lot of options. I also think Watmore has been held back since his covid experience.
Even though it's a tough game I would expect 1 of Kebano, Bolasie and Mendez-Laing to start. Kebano has only had one training session, so would expect him on the bench. Mendez-Laing hasn't been training professionally for 6 months so will probably be on the bench, so Bolasie will get the nod for me.
