Antonio Conte employed a 3-4-3 system in his two years as Chelsea manager, with Marcos Alonso as the left wing-back and Victor Moses on the right.
However, new Chelsea boss Maurizio Sarri is a 4-3-3 man and is expected to scrap the three at the back system. This has raised fears about Moses’ position under the Italian, and former Arsenal midfielder Stewart Robson believes Moses will lose his spot under Sarri.
Robson said: “He (Sarri) played with a normal back four. The wide players were attacking players and Moses was an attacking player to start with.
“I think Alonso could play as a left-back, I don’t think there’s any problem with that. The Napoli left-back used to get forward with great pace and get crosses in and Alonso can get back as well.
“Moses will be the player that will have more of a worry getting into the side at right-back but Sarri is a top class manager.
“He developed a style of play that was enjoyable to watch and successful and he had wide players that made different runs to the runs other people make.
“They were almost running into areas where there wasn’t enough space but the balls still kept being played in to them and they still got on the end of things. I’m looking forward to watching Chelsea play this season.”
