Charlie Adam has hailed Steven Gerrard as the greatest footballer he's ever played alongside as he prepares to lock horns with the Liverpool captain when Scotland take on England at Wembley on Wednesday.

The Stoke City midfielder spent a year in the company of the Reds' iconic No.8 during his spell at Anfield and admits it was an experience he'll treasure.

"On and off the pitch, he is one of the real gentlemen in the game," Adam said.

"I was fortunate enough to share a dressing room with him and to see him at close-quarters. It was an honour to play beside him.

"He is the best I've played beside, without a shadow of a doubt. He is probably one of the top players in the Premier League over the past 10 years.

"There was a full house at his testimonial the other week and everybody at Liverpool adores him.

"Most importantly, he is a nice guy."

After joining from Blackpool in the summer of 2011, Adam made 37 appearances for Liverpool before moving to Stoke last August.

The 27-year-old confesses trying to impress Gerrard was one of his main objectives upon arriving at Melwood.

Adam added: "Guys like Steven are the type of players you want to impress as they are iconic players at the club.

"You don't play for Liverpool for the number of years that he has if you are not a good player.

"He is a great lad and it will be a challenge for me to come up against a player like that.

"I have done it once or twice and, hopefully, I can get the same result as I have had before against him."
