Jesus Christ, why are you bringing effort into this? No one said he doesn't give everything, but last I checked, trying hard wasn't the cure for ageing.
Why is it you think accepting a 33 year old isn't going to be at peak fitness after a 54 games season with no break is some sort of personal attack on Fernandinho's character and his status at the club?
Weaker because our only defensive midfielder is now 33 and had no rest - the same midfielder who took 6 months break from playing well in 2014 because he was knackered after the last world cup.
We've gone from a fresh 32 year old fresh Fernandinho with old Yaya as an emergency to....33 year old knackered Fernandinho with no cover.
