Former Arsenal winger Paul Merson has described Super Eagles forward Victor Moses as an important player to Chelsea this term, much as Diego Costa and Eden Hazard.
Moses has strived from an unfamiliar right-wing back position, scoring three goals in 19 Premier League appearances.
And Merson, a Cup Winners' Cup winner with Arsenal in 1994 and a member of England squad to France 1998 World Cup, posits that Moses is key just like Costa and Hazard to the success of Antonio Conte's 3-4-3 formation.
"The stuff he puts in! You talk about Eden Hazard and Diego Costa, but Moses has been as important as anyone in making this system work for Conte and he's also scored some important goals," Merson told Sky Sports.
"To consider he'd never really played that role before is just incredible," Merson said.
