Players need to take a long hard look at themselves , bar maybe 2 players that was our best team on paper, and they can't be arsed to put in the effort, Fernandinho was our best player today, but that was cause he had to play well since Yaya wouldn't even bother to get goal side. 2 seasons now where we won the league the year before and the next year the players show no desire to get it back, I hate for us to sack our manager after 2 years after winning the league in one of those years but it needs to be done for us to move forward both in the champs league and the prem, Klopp would be the one for me as he would be a different type of likeable manager with his passion carrying over to the players and would also get into them a bit more.
I think it would be too much of a risk to out Viera in charge as he isn't proven and I still trust in Pellegrini to get a top four place but possibly next year he can be given a job as assistant manager.
In the summer we need to look at the squad properly and decide who we need to sell and get the right price, I would like to see Yaya bed in his successor but after the season he's had, which hasn't been bad just not like last season, says to me that he's on the decline and at this moment I would cash in, although that is the only one of our spine (Hart, Kompany, Yaya, Silva, Kun) that I would sell, but I would definitely look to improve other areas of the team with younger, quicker players that can produce something that can get the crowd of their feet even if we're not playing well.
One thing I would say is if we have a squad revamp then we have to accept that we could have a season of transition next year.
