Jose Mourinho has hinted that Chelsea will make a third attempt to sign Wayne Rooney before the transfer window closes.
The Blues boss has made no secret of his desire to strengthen his attack, and has seen United dismiss two bids for Rooney, who is understood to crave an exit from Old Trafford.
The Special One inherited Fernando Torres, Romelu Lukaku and Demba Ba when he took over at Stamford Bridge, and said soon after his arrival that Rooney was his only target.
Despite the fact that United insist Rooney is not for sale, Mourinho says there is no harm in trying to sign him again.
"You try, because nobody forbids you to try. 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,” he explained.
“The player's owners they can do exactly what we did in relation to David Luiz and Barcelona."
But Chelsea fans should not dismay if United send Mourinho packing again.
Samuel Eto’o has excitingly been linked to the Blues, and Mourinho admits that if he cannot get his first-choice striker, he has a few other tricks up his sleeve.
"We have plans B and C. Don't ask me names because it's difficult to speak about players from other clubs," he said slyly.
