England must improve their set-pieces under Eddie Jones if they want to have any success at the Six Nations, according to Mark Cueto.
During the Rugby World Cup England were uncharacteristically wasteful at scrums and line-outs, a contributing factor to the disappointing exit in the pool stages.
That elimination proved to be the end for Stuart Lancaster, with former Japan coach Jones replacing him in December.
Jones' tenure begins this weekend against Scotland at Murrayfield after two intensive weeks of training with his squad, and Cueto - who won the Six Nations with England in 2011 - believes improving their set-pieces should be high on the new coach's priority list.
"I know at a World Cup it's all about winning but we seemed to go backwards," Cueto told Omnisport.
"Probably one of the first issues he'll want to tighten up is the set-piece.
"England have always had a team that is very strong in the set-piece - [they have been like that] for decades - and even under Stuart Lancaster's reign they were good at the set-piece.
"But during the World Cup that got put under a lot of pressure and for whatever reason we seemed to have a real dip in form at the scrum and line-out.
"Rugby is a simple game - it doesn't change - your platform that the forwards provide is key to the backs being able to play with the ball in hand.
"So that will definitely be something that Eddie Jones will look to strengthen, and I think with the likes of Steve Borthwick coming in I'm sure he'll do a fantastic job at that."
