England flanker James Haskell believes their defeat to France in Paris will act as a wake-up call for the team ahead of the upcoming Rugby World Cup.
Stuart Lancaster's outfit lost 25-20 to les Bleus on Saturday and were second best is most aspects until a late surge led by Danny Cipriani brought them close.
The line-out and scrum were two areas of concern while errors and a lack of ball gave France a platform to impress, especially in the first-half, leaving back-row forward Haskell eager to learn from their mistakes ahead of facing Ireland.
"I think the first-half was one of our worst performances as a team," he told englandrugby.com.
"I think credit to France, they obviously came out on their home ground to do some damage today and I thought they were great.
"Obviously we couldn't get any ball to play with and we spent a lot of time defending. Even though the boys worked hard, you can't give a team like France that many opportunities because they will just keep kicking the points."
He added: "We didn't win the ball, we weren't as direct as we should have been."
Haskell admitted England would need to reflect on the loss before taking on the Irish in Dublin on September 5.
"I think the boys will use this as a wake-up call and go forward positively. The best thing about this group is we are very honest," he said.
"We have got tomorrow off and then in for a big work week. The boys will put their hand up, we will work extremely hard and we will be very honest."
