I think Liverpool and United will scrape the top 4 to be honest.
Liverpool are on terrible run, but I'd be amazed if they slip into relegation form for all of the 2nd half of the season. As much as I'd like it, I don't see it happening. Whilst they moan about injuries they still have a decent team. That said, Klopp is finished there. He's made the mistake of playing the same players week-in-week-out and not rotating. It's as if he's never studied Wenger, Ferguson, Guardiola etc. He's fell into a trap where his players are absolutely knackered with way too many miles on the clock. He won't be able to rebuild that team without serious money and I can see him going to Madrid in summer.
United have a decent team, but are held back by their amateurish manager. If they'd got a manager in like Ancelotti I'm sure they wouldn't be 10 points behind us.
