Gabriel Sutton admits it's a tricky one to call - 'I've thought a bit about this game and I'm having a tough time calling it. Last week, Arsenal took a massive step backwards in terms of the title race and in giving away two easy goals from simple set pieces- it was back to the same old Arsenal. I remember Allardyce seemed to enjoy managing against Arsenal with Bolton and his West Ham side taking quite a direct, high-tempo approach, I think they could cause Arsenal's defence problems. If you bear in mind this is a derby game as well, that West Ham are above Arsenal in the table and that it's played at Upton Park, I think a draw is the best shout.'

Ant, the Gooner from Portsmouth, has written in to say - 'Fancy us to the 3 points today and carry on our very good away form in the league so far. Seem to play with more freedom and confidence away from the Emirates and am going for a 3-1 away win with Giroud grabbing his first goal as think he may well start today.'
