Fulham midfielder Dickson Etuhu has revealed both he and team-mate Bobby Zamora have been undergoing unusual treatment in a bid to speed up their recovery from injury.
The pair have resorted to specialised oxygen chambers as Etuhu fights ligament damage while Zamora recovers from the broken leg sustained against Wolves last month.
The method is a measure of how far sports science has come in modern football and Etuhu expects to be back early next month thanks to the treatment.
"I believe I will be back in three weeks," Etuhu told the News of the World.
"I've been using the oxygen chamber at a hospital. It's like a small submarine, but when I come out I feel great.
"Bobby is using one at Fulham. It's smaller, like a coffin, but he's in there every day. I used the same treatment about 15 months ago when I'd torn a quad muscle."
Zamora's untimely injury came almost immediately after he put pen to paper on a new deal at Craven Cottage and Etuhu admits the sooner he gets back to fitness the better.
He added: "Bobby is a massive loss to us and we need him back as soon as possible."
