It's fine if it's a few beers. No harm done. If it was a serious session, then it's not cool. Don't see why they have time off to fly out there though. Should be back in Liverpool training. Or getting physio if they're injured. Flying out there and walking around doesn't seem like the best way for Carroll to fix his knee.
Who said they went instead of training/physio? It's not like they train 24/7. Carroll hurt his knee therefore he should sit on a chair at home like an invalid? When did you become their mother?

Frankly having a few hours to unwind together is actually really good for team spirit, and I'm glad Pepe was with them.
