Tbh the form he's shown over the past 2 season he should be concentrating on his place first before we consider him captain
He hasn't been that bad.
Not lived up to his usual standards, no, but he's struggled with injuries and I think it's pretty clear his impact going forward was nullified once Martinez managed to get his system in place.
It's a clean slate now.
For what it's worth, Seamus is probably the only player to have improved defensively over the past two seasons.
He'll be back to his best this term, got no doubt about that
