I don't buy this easy / difficult game business. Generally all teams in the PL need to perform at or close to their best in every game to get a result. Drop a little and you lose, and that includes the top teams, given the league is so competitive. See it all the time, from all teams, where they pick up points you would never expect and lose points from what would be considered a 'banker'. Just play each game to best of ability and at the end of the season you arrive at the league position you merit.
