This will be an unpopular opinion I'm sure, but I'd rather Llorente started tonight.
I know he's been poor this season, and I do rate Morata, hear me out.
When we played Bayern Munich a couple of seasons ago, one of the reasons we couldn't cope with their pressing is we had no out-ball. Matri and Quags didn't provide a physical presence, so we couldn't go direct to them.
That meant that we were trying to play out from the back, but as with all Italian teams, couldn't cope with the furious pressing.
I think tonight we'll be ok, if we can weather the first 10-15 minutes of their pressing, and get time to impose ourselves on the game. But I think for that initial spell, we need to be able to go direct to the front, and Llorente is more suited to that role than Morata.
Morata can come on nearer the end, when his pace will trouble their tired legs after they've been pressing so hard all game.
