England head coach Eddie Jones believes there is not an easy fix to his side’s problems after they fell apart against Scotland on Saturday.

The Twickenham hosts raced into a 31-0 lead and held a 31-7 cushion on 46 minutes before the Scots launched their fightback to eventually draw.

It was unthinkable at the time that Gregor Townsend’s men would recover from such a deficit but England crumbled and were lucky not to lose.

Jones believes his charges are suffering with a mental issue that is allowing teams back in to games, citing previous matches over the past year, and is determined to resolve the issue before the Rugby World Cup.

“It’s a re-occurring theme for us and we’ve probably experienced this three times over the past 12 months where we’ve let our foot off the gas and haven’t been able to get control back,” he told England Rugby following the 38-38 draw.

“Our first half was exceptional and we came in at half-time determined to tighten things up but we failed do to that.

“I thought our finishers did exceptionally well to get us out of jail, but I’m disappointed with the 80 minutes.”

Jones added: “We lack the discipline to do the simple things over and over. We got seduced by the scoreboard.

“This is possibly a problem the team has had for a long time, even before I started so we need to make sure we get the right people in to help us. It’s 100 per cent mental, it’s the way you think and we’ll get that right.

“It’s not something you can fix easily, it’s going to take some digging deep into the team’s psyche. We think we’ve got a pretty good idea of what it is, but it’s going to take some time.”
