Robbie Keane is using an ice chamber to get fit for West Ham United.
The Sun says the Hammers are using an ice chamber to speed the recovery of striker Keane from a calf injury.
Team-mate Jack Collison has also been using the chamber as he recovers from knee surgery.
Midfielder Collison said: "Robbie and I had to sit in the chamber at minus 140 degrees for five minutes at a time.
"We had to share the chamber with boxer Frank Bruno. It was great to meet him but he made us look really weak as he was in there doing all kinds of exercises while Robbie and I just sat there trying to keep warm."
