We should prioritise the next 3 league games over all others imho, and take maximum points, however we need to take each game as it comes, and see what is available, playing the strongest possible team in all the games.
We have 2 winnable league games, and we need to take 6 points. We then follow up with 2 cup games, one of them is important to our league campaign too, because beating Chelsea in the FA Cup will tell them we're still in business.
The Barcelona home game comes at a difficult time, and I would aim to keep that as tight as possible, it would be great to have a lead, but a draw is no disaster, as the second leg is over a month away, and we have a good chance over there, even if its level.
Then another winnable league game where we must take 3 points again. assuming we don't draw with Chelsea (the worst result of the three imho) we then have a week off, before a cup final, which its important we can put out our best side possible.
So for me the league should remain the priority, and that includes beating Chelsea in the FA Cup because its a marker for the league.
We dreamt of times like this only 5 years ago, so lets grasp them, and enjoy them as much as possible, and we have no idea what injuries will beset our rivals.
