Chelsea manager Jose Mourinho has hinted he will continue his pursuit of Manc United striker Wayne Rooney until the closure of the transfer window on September 2.
The Blues have already had two bids for Rooney rejected by United, with David Moyes insisting the striker is not for sale at any price.
Chelsea are set to test that resolve once more, perhaps even before the trip to Old Trafford a week tonight if Mourinho is feeling mischievous.
"We will try till the last day to add a new player to the squad, a striker, but in this moment every striker has a club, every striker belongs to somebody and I don't think it's ethical that I name players that belong to other clubs," said Mourinho, following Chelsea's 2-0 defeat of Hull on his return to Stamford Bridge yesterday.
"We don't try, like many clubs do, to go around and try to influence players to behave in a certain way.
"If we have to make a bid, we make it in an official way, we don't speak to players, we speak to clubs."
The self-proclaimed Special One was enthused by the first-half performance, in particular, on his homecoming.
Goals from Oscar and Frank Lampard, who also had a penalty saved, saw Mourinho's men triumph in an incident-packed match which saw goal-line technology employed in the top-flight for the first time when Allan McGregor saved from Branislav Ivanovic.
"I played so many times here, I won so many matches here, but we didn't have so many periods of such fantastic quality like we had (against Hull)," Mourinho said.
"I'm happy we managed to win and we managed to show that this is the football we want to play, this is the football we can play.
"Now it's up to us to make it happen more times and more times during the game."
Mourinho, who left Chelsea in September 2007, returning to win with Inter Milan in March 2010, described his reception as "amazing" before calling on supporters to throw their energies behind the team in Wednesday's Premier League clash with Aston Villa.
Hull manager Steve Bruce selected five players for their competitive debuts, but Tom Huddlestone and Jake Livermore - signed from Tottenham on a permanent and loan basis, respectively - were not among them.
Instead the duo came off the bench, making an impact in an improved second-half showing.
"Believe it or not we've been trying to work on a system to play against Chelsea for the last two, three weeks," Bruce said.
"We've only had them 48 hours, really, and also you have to be kind to the players who got you here, from rainy nights in Barnsley.
"(But) make no mistake the two boys from Tottenham will make a huge difference to us.
"And we've got many games to play where we won't be playing Chelsea every week, thankfully."
