Keane's imminent £13 million move to Serie A giants Internazionale, will leave manager Gordon Strachan with a major headache as to who will take over the goalscoring duties at Highfield Road.
However, suggestions that prolific West Bromwich Albion star Lee Hughes could be targeted, have surprisingly been confirmed by chairman Richardson.
"He's one we are looking at," said the Coventry chairman, to the club's official website. "There are a lot of names in the pot at the moment, but I've not spoken to Gordon Strachan about spending the money yet."
Hughes, who has seen a new strike partner arrive at The Hawthorns in £2 million man Jason Roberts, has already been subject of a failed £3 million bid from Birmingham City, but the prospect of Premiership football could be the spur to tempt the striker away from his beloved Baggies.
The knowledge that Coventry have money to spend could feasibly lead to West Brom raising the fee for their star goalscorer - although they remain confident that they will keep hold of Hughes.
Hawthorns chairman Paul Thompson insisted: "We do not wish to sell Lee Hughes and we're not looking to. If Coventry wanted to offer us £13million of course, then that would be different."
