In July the Portuguese claimed the 27-year-old was his only transfer target but now admits he has other options as he remains determined to bolster his attack this summerChelsea manager Jose Mourinho has revealed that he has a back-up plan if his pursuit of Manchester United striker Wayne Rooney fails.

"We have plans B and C," he told reporters. "Don't ask me names. It's difficult to speak about players from other clubs.
"We have the conditions to try to improve our team by bringing in one more player and we are going to try that till the end."
Samuel Eto'o has been heavily linked with a move to Stamford Bridge in the past week, having been among a number of players told they can leave Russian side Anzhi Makhachkala this summer.
But Mourinho insists he will not give up his pursuit of Rooney until the transfer deadline, despite United's bullish determination to keep their prized asset.
"You try, because nobody forbids you to try," he added.
"When you think that you'd like to have one player and the market is open and the official bids are not forbidden, official bids are always accepted in an ethical way.
"Of course, the player's owners can do exactly what we did in relation to David Luiz and Barcelona."
