Jose Mourinho has reserved special praise for Andre Schurrle after the German international lit up the tie against Steaua Bucharest.
Schurrle signed for Chelsea from German side Bayer Leverkusen this summer in an £18m deal.
Since then he has struggled to justify that fee with a series of underwhelming performances marring his early days at Stamford Bridge.
However, the 22-year-old finally appears to be settling down in west London and has started showing what he is capable of, most notably in the Champions League game against Steaua Bucharest last night.
Mourinho has been quick to heap praise on the German international, saying that he was "monumental" against the Romanian side.
He said: “He [Schurrle] was monumental.
“He identified very well what we had to try to do and penetrated the Steaua defence. He was immense.
“He was playing a position where we knew he could [do well] and he came in a lot from that side."
Mourinho also revealed that he has been experimenting with Schurrle's positioning, confirming that he tried him on both the left and right wings in an attempt to work out his most dangerous role.
"His best position is on the left," Mourinho said. "In other matches he has played on the right, which he was trying to deliver but he is a different player on the right than on the left.
"Against Tottenham he played very, very well and had a big chance to score and for us to win the game.
"Today he started from that position and people understand the quality he has.
"He was getting balls in space and on his feet, getting space to attack the defender - he was very strong."
Mourinho was speaking after Chelsea's 4-0 thumping Steaua Bucharest to get their first win of the this season's Champions League.
