Everton is a team in free fall and Roberto has lost the plot. After getting run over by Liverpool, I don't think this Everton team really cares about the rest of the season. The only danger is Lukaku but I think Smalling will handle him
Manchester United are on a roll and Rashford is on fire. They've finally got back most of their injured players.
As for palace and Watford, it would take a miracle for them to beat United. If worse comes to worse, De Gea will bail them out in a penalty shootout. These teams are pretty stale and in a parking the bus scenario, I highly doubt United will come out as a loser.
