Roeder insisted Di Canio had not been affected by the on-going transfer talk.
"Paolo has been flying in training," said the West Ham boss.
"He loves his training and once he gets on that training ground he is the ultimate professional.
"He has not been affected by everything that is going on and I'd have no hesitation in picking him to play on Saturday."

"It's up to us to show everyone that this club still has a fire in its belly, a desire to be successful and a willingness to overcome the odds."
