The Republic of Ireland international has been a favourite of McCarthy’s since the 2002 World Cup in which the Yorkshire-born head coach managed the Irish in the finals.
Keane is said to be being tracked by a number of Premier League clubs after Tottenham manager Harry Redknapp admitted that he was struggling to find a place for the £5m rated 30-year-old.
The former Liverpool forward began his career at Molineux and may be persuaded to return to help the struggling Midlands club avoid relegation, but McCarthy knows encouraging the Republic of Ireland striker will be a tough task.
“He [Keane] is a fabulous player,” McCarthy told the Daily Mirror.
“But would he want to come to us? Can we afford the deal? Is it attractive?
“Robbie has been a top player and whether a relegation scrap at Wolves is something he would fancy, I don’t know.
“There are a lot of factors that need to be looked at. It is not just a question of whether I just want someone.
“We will keep looking at players and the ones that we can get, if they are available, we will do it.”
Keane scored 29 goals in 88 appearances for Wolves where he began his career in 1997. Stellar performances for both Wolves and eventually Coventry City won him a surprise big money move to Inter Milan where he struggled to make an impact. Keane has enjoyed the majority of his success at Tottenham where he returned following a problematic spell at Liverpool.
