Chris Gunter believes he, Aaron Ramsey and Gareth Bale can shake off the disappointment of heavy weekend defeats with their clubs while on Wales duty.
The trio are preparing for Gary Speed's side's European Championship qualifiers with Montenegro and England.
Gunter's Nottingham Forest lost 4-1 to West Ham and he said: "We've moved on."
Defender Gunter is sharing a room with Ramsey in the build-up to Friday's clash with Montenegro at Cardiff City Stadium.
The duo met on Sunday night as Wales' squad gathered and Gunter says they lifted each others' spirits.
"You can laugh about it now, but it was obviously a really bad weekend for a few of us.
"You learn to get over disappointment as quickly as possible and coming away has probably sped that up a bit and now we're looking towards two important games.
"Driving here after the game on Sunday - you don't wish that on anyone. It's a terrible feeling.
"I stopped off at home for five minutes to get my Welsh tracksuit and stuff and I suppose if you ask my mum and dad I didn't say more than two words to them.
"And it's horrible.
"It's a feeling that sometimes you go through as a footballer - you lose games, it's not a rare thing.
"The manner, on Sunday, is disappointing and obviously the same for Aaron - you never lose by that scoreline.
"So it takes a couple of days, but you have to try and forget about it because there's nothing you can do.
"You can't play the game again and being here is a different situation because I didn't go into the club the next day.
"It is a case of just trying to forget about it and move on and in football there is another game, albeit it's with a different team.
"You do get used to it and you have to try and block it all out.
"But there's always jokes and stuff like that and it sometimes helps to get over it.
"I think now we've moved on and are looking towards the training this week and obviously two massive games."
Having dropped to a record low of 117th in the Fifa world rankings, Wales now face Group G's two pace-setters, with both Montenegro and England unbeaten on 11 points.
