"At the break we told the players that we had to take risks, that without taking them we would end up with nothing," the Brazilian tactician told a press conference after the game.

The Turkish giants came from behind to beat Chelsea 2-1.

"If we show the same attitude in England then I believe that we will get the result that sends us through to the semi-finals."

The return leg will be played at Stamford Bridge on April 9.
