Of course!
If Jose fails to win the Europa cup, then I would be the first person to say Mourinho out.
Imagine if he lined up a strong team today and Rashford, Pogba and Bailly suffers a gruesome knee injury....you people would be saying it's poor man management.
A win against Arsenal today does not guarantee top 4. It only improves our chances. Why not go full blown on a game that massively increases our chances of playing CL next season?
Just like winning against Celta does not guarantee top four, it only improves our chances. There's still strong teams left in the fixture list like Ajax. Yes, Why not go full blown on a game that could have got us closer top 4 if another route doesn't work out?
Where are you getting Bailly? He wasn't even in the team line up.
