Wales manager Chris Coleman said he will take his time in making a decision about his future. He said he will let the 'dust settle' before having a conversation about his situation.
Wales' hopes of qualification were ended by a 1-0 defeat in Cardiff sending the Republic of Ireland to a World Cup play-off.
Wales lost for only the second time in 22 qualifiers with the absence of star man Gareth Bale..
The moment came in the 57th minute when Wales skipper Ashley Williams lost possession on the edge of his penalty area and Jeff Hendrick crossed for McClean to slam home his fourth goal of the campaign.
Wales needed a victory to reach next month's play-offs and raise hopes of a first World Cup finals appearance since 1958.
But despite fierce pressure at the start of each half, Ireland held firm and accepted the game's best opening when it came.
Wales had won three successive games to put play-off destiny in their own hands, but this defeat could mark the final game of Chris Coleman's six-year tenure as the manager has said this would be his last campaign.
