I'm gonna play the controversial card with this one and suggest that we should 'rest' Pelle and give Long a crack at centre forward.
So....assuming Morgan won't be 100% and Cork has recovered from his illness, I'd go for:
Forster
Clyne - Fonte - Alderwerield - Bertrand
Cork - Wanyama - Davis
Mane - Long - Tadic
Subs: K Davis, Yoshida, Gardos, Reed, Schneiderlin, Pelle, Mayuka
