Interesting question. As always I think the bookmakers at least manage to ballpark probability figures like these. Lowest odds I could find on oddschecker for the two were:
To win the league cup: 7.5 (13/2)
Top 4 finish: 7 (6/1)
So very close. For the bookmakers at least.
For me, at this stage of the season we have to balance our interests. Rotate a bit, be smart about it. It's most likely what we'll have to do come the new year if we keep progressing in the Europa League. It's what we should do now with two fairly closely balanced priorities.
That's interesting re the odds.
I should have add in the cavaet that i'd expect us to keep the same approach with regards to rotation as we currently seem to have - but fitness aside i want to see a 'first team' not a patch up job with unfamiliar partnerships all over the pitch.
As someone else mentioned, win this the semi's are on, avoid Chelsea in that draw and there should be a good buzz around the place
