Chelsea coach Luiz Felipe Scolari is searching for a player who will make all the difference.
He admits Chelsea are struggling at home this season despite having won all their away matches.
The Blues were close to signing Robinho but surprisingly, he signed for Manchester City. Chelsea have earned praise for their brand of football this season but Scolari says his team need to be more flexible.
"We have a style of play and we need to change that sometimes," said Scolari.
"We will change that style when we have a player with a different style.
"When I came to Chelsea, I said I wanted one player who is different - someone who'll try something different when we play against teams who close us down.
Chelsea's long unbeaten home record came to an end with a defeat to Liverpool last weekend and they have dropped points in two other matches at Stamford Bridge.
Scolari said: "It's easier for us to play away because opponents open up more and give us more chances" said Scolari.
