Assistant coach Rob Howley says Wales are "all in it together" following their 25-21 Six Nations defeat to England on Saturday.
The loss at Twickenham ended their hopes of securing a third Six Nations title in five years, with England being crowned champions after Scotland's win over France the following day.
The final test for Warren Gatland's side is a home encounter with Italy on Saturday. Italy have never won in Cardiff and another victory for the Welsh would guarantee them the runners-up spot in this year's championship.
After seeing England race into a 16-0 lead at the weekend, Howley said: "It is about looking at yourself in the mirror, coaches included, and asking yourself the questions about the first 20-25 minutes.
"Rugby is a game of emotion and unfortunately, we just didn't start well. Have I got the answers? Not at this moment in time. Hopefully, over a period of time when we have spoken to the players individually and collectively as coaches, we might have some of those answers.
"As coaches and players, we are all in it together. It's not just the players, it's the coaches, the backroom staff. When we play for Wales, all of us are playing for Wales, so please don't try and divide and conquer here in terms of players and coaches or the management team. We are as one.
"When you are 16-0 down after 25 minutes, playing against England, it becomes quite frenetic, the pictures are moving very quickly and you do things sometimes which unfortunately you wouldn't normally do if you weren't under pressure on the scoreboard, 16-0 down.
"The second half, we actually beat England 21-9 on the scoreboard. We scored three tries to one. But unfortunately, the first 20 minutes in terms of momentum had a huge influence. I am sure many conversations will happen over the next 24-48 hours."
Wales head coach Gatland is due to announce his team for the Italy Test on Tuesday, with at least a handful of changes expected.
"When the bench came on, there was certainly a change in the momentum of the game, and they made a huge impact," Howley added.
"I think we've got some decisions to make, and that is down to Warren to decide what changes are felt necessary for the weekend. I don't know what Warren is thinking at this moment in time. Over the next 24 hours, we will decide in terms of that selection."
