Fulham have completed a deal for Czech keeper Jaroslav Drobny.
Drobny will join in the summer from Greek club Panionios.
“Drobny will give me three first-team keepers to choose from,” said Coleman.
“He’s got good hands and is at a good age, so will only get better.
“I was impressed by his attitude when I met him and I’m looking forward to his arrival. It will be good for Mark and Edwin to have some more competition.”
Meanwhile, Coleman has also confirmed that he is looking to recruit former Scotland manager Craig Brown to Craven Cottage.
Coleman denied that Brown would be employed as a director of football, but would like to see him oversee the club’s scouting network.
“I don’t believe a club should have a director of football,” said Coleman.
“I don’t want someone above me bringing players in that I didn’t know about, and I’ll never change that view.
“Instead, I’ve been talking to Craig Brown because of his connections in Europe; he has incredible experience as a former international manager.
“We’re looking at bringing him in a scouting capacity, he wouldn’t have anything to do with the academy and would not be director of football.
“We need a bigger scouting network and should be searching for players in Europe a bit more, this is something we’ve been thinking about for some time.
“We’ve been looking at different people but Craig seems perfect for the job. It would be a real coup if we managed to persuade him to join us.”
