Sky Sports' pundit Paul Merson predicts...
After a difficult few weeks Liverpool had a good win at Bournemouth and showed glimpses of their former selves. But to be honest if you had to pick a game for them to play then that would have been it, I don't think there was more than two tackles in the whole game.
They're not the team they were and Arsenal have Sanchez so both teams won't be able to cope with each other defensively. I'm going for a thrilling Desmond with lots of action on the cards.
PAUL PREDICTS: 2-2
