I'm pretty sure Jose thinks this game is more important than the Chelsea game, even if it's easier. Europa League is a potential route to the Champions League, the FA CUP isn't.
Not sure about which he takes more seriously, but this is half a game in effect, being a two legged affair, so I think he will see tonight as a damage limitation exercise and play for a draw. The Chelsea game is a completely different situation and yes, I think he will have half an eye on that - for example by NOT playing Miki.
I wouldnt characterise it as him taking the Chelsea game more seriously though. If he could only go through in one I would imagine he would choose the EL.
IMO the Chelsea one is more important to him. FA Cup is one off and his pride needs some boost.
I think he'll take both equally seriously (he did say when the draw was made he'll play strong team vs Chelsea). Lineup for this might be slightly weaker though with him not wanting to risk injuring some players (watch him start Valencia now)
You people are not helping me!
But thanks for replays, will have to submit my line up soon, so I will go with half good half bad, think he might play Felli, (oh dear Lord) and Darmian instead of Valencia, (God help us), and some more changes, because, like Adebisi said, it it 2 games, and pretty sure if the pitch was better he would play best team, but he might have Monday on his mind and any injury.. I think he wants to do good at SB, you know, ex team,and Conte celebrations, that is why I am so confused.
But score draw and no injuries, and I'm a happy.
