Chelsea duo Lucas Piazon and Tomas Kalas are currently on loan at Championship side Fulham, who are battling for a play-off spot.
Fulham captain Tom Cairney believes the Chelsea duo have made Fulham stronger this season.
“I just think they have made the squad so strong,” Cairney is quoted in Standard Sport.
“Kalas has been brilliant, especially at the start of the season.
“Lucas has just got a bad injury at the weekend but he is brilliant on the ball and has done well.
“We pass out from the back. It is risky football, if you make an error, don’t worry. You just have to keep on going and I think that’s why as games have gotten on we have got more and more confident and we are showing that at the minute.”
Piazon faces a lengthy spell in the sidelines after suffering a broken jaw in Fulham’s last match, a draw at Cardiff.
