Liverpool have no more work to do now that they have reached the top of the table and won the title this season. Arsenal need points to hold on to the runners up spot and I think Liverpool will give them that chance.
As for Man United and West Ham, both teams are in similar form at the moment and Man United will be at home and have an important schedule in the UEL final. I don't think Amorim will risk putting pressure on Man United players to win at home but a draw would be better than sacrificing the physicality of Man United players.
That's not the rule of the game, do you think Liverpool will give points to Arsenal just because Liverpool has become champions? This is like a pity match, where Liverpool's pride will be put on the line if they have to give up so easily? Basically Arsenal should fight with their strength, not beg for points from Liverpool. Manchester United have no mission in the Premier League this season. Losing or drawing will not change anything for them. Amorim remains focused on the Europa League as he said.
