Chelsea officials couldn't resist a pop at Arsenal during yesterday's open training session.

Over 6,000 fans attended the event to see new manager Guus Hiddink put Chelsea's players through their paces.

Hiddink said: "I hope to make a very good end of this season. We need your support. I'll give you everything I have to make the team work."

The PA announcer also tried to lighten the mood, says The Sun.

He quipped: "Arsene Wenger is planting potatoes in the Emirates' goalmouth so he'll have something to lift come May."

The crowd groaned at the gag.
