Roy wasn't good enough for the job, anyone could see that after a couple of months. Dalglish will succeed in getting them playing decent football and get them into the top 7 at least. He's been watching every match and probably has the best football brain in the country still. Just watch them rise again. I'm guessing Deschamps will arrive in the summer.
I agree with Dalglish bringing decent football and more pride to the side, and I think top 8 is a realistic target for the season. But Deschamps has already rejected Liverpool recently, Ragnick or Coyle are my likely candidates.
