The trio have been out of the first team picture for varying degrees of the season, and have found themselves confined to the reserves in recent weeks, prompting speculation that Keane wishes to discard all three of the under contract players in the summer.
Fan favourite Counago has started 12 games and come on as a sub 17 times scoring 3 goals this season, but has not been included in the last five 18 man squads on match day, with Town boss Roy Keane on some occasions choosing no specialist striker on the bench rather than including the Spaniard.
Youth academy product Garvan has failed to hold down a first team place for much of the campaign despite much promise in recent years, and this year has started just 15 games, and coming on as a sub 12 times in what has generally been a stop start season for the Dublin born midfielder.
Meanwhile former Manchester United midfielder or striker Lee Martin has played just five games since 20th October, starting one and being a substitute in an additional four games as he has failed to live up to ths six figure sum that Town paid for the Taunton born player.
Speaking to the Official Club Website, Keane said: "It's important that we have a reserve team full of young players next season. We have had senior professionals playing for the team lately, lads like Pablo, Garvs, Lee Martin and they are too good for that level."
