Cresswell has shocked many at the Boleyn Ground with the standard of his performances in his first year at the top-level.
The left-back was brought in from Ipswich Town last summer and has been one of the Hammers' star performers, with Dicks reserving special praise for the 25-year-old.
"One player who I have been impressed with is the lad who is filling my old position at left-back, Aaron Cresswell," he said.
"He is a good player. When he first came along, I watched him at Ipswich Town and he likes to get forward on the overlap and join the attack and that’s what we had been missing.
"No disrespect to the left-backs we’ve had before, but you need your left-backs to go on the overlap and help your strikers and your wide players and midfield players. Hopefully he will keep improving and be here for a while."
Cresswell has offered West Ham a potent attacking outlet, while he has also been secure in defensive scenarios, making him the complete modern day full-back.
His performances are reported to have caught the eye of some of the country's biggest sides though, and there is now a question mark over his future.
The Manchester Evening News suggests that Manchester City will make a bid for Cresswell in the coming months and if they do, West Ham could face a fight to keep him.
City have more financial power than most teams in the Premier League and if they did seriously set their sights on signing Cresswell, it would be hard to see him staying at the Boleyn Ground.
That said, West Ham clearly are determined to give themselves the best chance of keeping him for the long-term, with the Daily Mirror reporting that they plan to offer him a new contract in the near future.
