Wouldn't be fair to 'guess' the 1st one
2.) I'd like Liverpool ofc, but that's way too expensive. I like the Luton shout from bullrun2020bro, new teams in the league are always interesting to track.
Although I'm all Liverpool, I do like Newcastle as a club - they've got a huge and loyal fanbase, are a proper english team and they have invested smartly and are managed fantastically.
3.) I'd love Ajax. Borussia Dortmund as well, of course - clubs with a proper footballing tradition but not the european cream - I don't really like the Barcelonas and Chelseas of the world.
4.) Soton - Liverpool, ofc. Or Soton - that new club I hope you get!
EDIT: obviously, I meant in the Cup - considering that Soton is in the Championship. In the league probably Leicester?
