WHAT THE MANAGERS SAY
Arsenal manager Arsene Wenger denies reports he has agreed to extend his stay beyond next season: “That’s completely wrong. You can treat that as just an invention and no more.
“What I focus on is respecting my contract and then envisage what I will do afterwards. I will see where I am personally and where the club stands at the end of my contract.”
The biggest decision I’ve got here is whether Arsenal will win 3-0 or 4-0.
