Six Nations 2016: England coach Eddie Jones sends warning ahead of grand slam tilt

England coach Eddie Jones has warned his side they have much to work on if they are to cinch a Six Nations and grand slam double against France in Paris next weekend. Victory over Wales at Twickenham was the fourth in a row under the Australian and sets up the tantalising proposition of a double success in the French capital in their final championship game.

Owen Farrell kicked 20 points including six penalties to put England on course for a comfortable victory and the triple crown until Dan Cole's yellow card opened the door for a Welsh comeback. George North and Taulupe Faletau scored in the final ten minutes in a dramatic climax to a contest which for so long was in England's control.

Should France fail to beat Scotland in Edinburgh on Sunday [13 March] England will be gifted their first title for five years before they travel to France. However, with the opportunity to end a 13-year wait for a grand slam on the horizon, Jones says his side must improve after standards slipped against Wales.

"The grand slam is on isn't it? So all we have to do now is prepare well," Jones said. "We know France will be passionate and playing with pride in their last game in the Six Nations and depending on what the result is tomorrow. All we have to do is prepare well and if we prepare well we'll play well and if we play well we'll have the Six Nations.

"What went wrong in the last 20 minutes is we missed a couple of tackles. We're always working on our defence and we're always looking on how to get better as a team. We don't need to focus on the first 60, we don't need to focus on the last 20 we just need to focus on getting better as a team.

"What we tended to do in the last 20 is sit back and instead of keeping attacking them and when we sat back and kicked back to them we gave them a little bit of ball we really struggled. There is nothing massively there we have to change just tactically we have to have more awareness on what we have to do."

With Wales chasing a further score to clinch a late win, it took replacement Manu Tuilagi's tackle on George North in the last minute to finally end Wales' hopes. Despite dominating the game for over an hour the game was on a knife edge in the closing moments but Jones is keen to focus on the positive aspects of his team's performance.

"What was significant was our first 60 minutes, I thought we played really well and I thought we played good position, played tactically smart and were physical," he added. "The last 20 wasn't great which is a really good learning experience for us. We had to defend with 14 men at the end. To get a win over wales, when you look at the history of the game we want to be two ahead so it is a good result for us.

"Rugby is a funny game isn't it? You miss one tackle and you allow them back in the game. One kick gets charged down and the game starts going their way. They get a few referee decision and the momentum flows and comes in the game. When you have momentum against you, you have to up your intensity and it was only in the last three minutes when we increased our intensity again and we had to. And we need to be better than that."
