Ferris and co. then threw away an 11-point half-time lead in Paris to draw 17-17 with France before registering four tries in a comfortable home win over Scotland last time out.

Saturday’s showdown at Twickenham, where England need a huge win coupled with a France victory over Wales in Cardiff to stand any chance of winning the Championship, is likely to decide who finishes second.

And Ulster’s Ferris believes England, fresh from a dramatic 24-22 win in Paris at the weekend, should expect the very best Ireland have to offer come Saturday afternoon.

"We are improving week on week and are happy with our set-piece,” said Ferris.

“We know England are strong at home and they won't concede any soft tries, like Scotland did, either.

"You have to be on top of your game to get a result at Twickenham.

"We have to chase the box-kicks down hard and get behind them. Rob Kearney is going to be busy in the air again.

"Since the criticism we took after the Wales game we've defended pretty well and overall we are defending and playing well.”
