Arsenal hero Paul Merson has warned Crystal Palace ace Wilfried Zaha off a move to a big six club.

Merson believes Zaha is playing the best football of his career after netting five times in nine games this season.

He wrote in his Daily Star column: "Wilfried Zaha plays every week at Crystal Palace.

"He can have a bad game and still start the following match and that might not happen at a Big Six club.

"I think he should seriously consider his options before running down his contract. He's a legend at Palace and the manager loves him.

"I see someone like Arsenal coming in for him if they get into the Champions League but do you go there and risk becoming a bit-part player?

"You're then going on a free. It's not like you're Darwin Nunez, who cost £85m and therefore has to play. Will he want to play for one week and then drop to the bench? I'm just not sure whether the grass is going to be greener for Zaha.

"He's playing the best football of his career and there is a reason for that. He needs to sit down and have a big think about his future."
