But, can they transfer that strong outing on the pitch to a strong outing in the transfer window this week?
Read on to find out what the Blues are rumored to be up to in the final weeks of the silly season.

According to a tweet by BBC Sport, Chelsea have agreed a £30 million fee with Anzhi for Willian.
Chelsea have agreed a £30m deal to sign attacking midfielder Willian from Russian club Anzhi Makhachkala subject to a work permit hearing

Just 24 hours ago, the Brazilian midfielder was undergoing a medical at Tottenham, but now he is set to be moving to Stamford Bridge instead.
Willian's deal is contingent on a work permit hearing, and if he passes that, he will join an already crowded Blues midfield.
Chelsea could be prepared to turn the summer transfer window on its head with their surprise bid for Anzhi midfielder Willian.
It was believed that the Brazilian was in line to join Tottenham after passing a medical, but the Blues have stepped in at the last minute to hijack the move.
According to John Percy and Chris Bascombe at The Telegraph, the Blues have made the bid for the 25-year-old in an attempt to have him in the squad for Monday's match against Manchester United.
The proposed late move for Willian could end up affecting the transfer market as a whole, according to Sami Mokbel of the Daily Mail.
"But Sportsmail understands Spurs chairman Daniel Levy is so furious about Mourinho’s £32m move for Willian that he is threatening to pull the plug on Bale’s departure."

Whether or not the Mata interest is a part of a potential Wayne Rooney deal is unknown at the moment says Delaney.
Adding to the drama around the Willian deal, Jose Mourinho has said at his Friday press conference:
"I think he's already made his decision."
The Wayne Rooney transfer saga has hit a new high according to numerous sources.
United have told the Blues that they will accept a bid for the English forward, as long as they have a replacement for him.
As for when that bid will be placed, BBC Sport claims that Chelsea will make a third bid for Rooney after the two clubs clash at Old Trafford on Monday night.
If Rooney does join the Stamford Bridge-based club in the final two weeks of the window, a forward will most likely be let go.
It would make sense for one of these two forwards to leave the club if Rooney is captured by the Blues.
The more logical choice to send out on loan would be Ba as Lukaku is poised for a breakout season at Stamford Bridge after thriving on loan at West Brom last season.
Wednesday's news about Chelsea focuses on the position that still needs some attention at the club, forward.
It seems as though the Blues' pursuit of Samuel Eto'o is over, according to Metro's Jamie Sanderson.
Sanderson's report declares that Anzhi coach Gadzhi Gadzhiev has stated that Eto'o has decided to stay in Russia and play for the club this season.
As if the silly season could not get more confusing, Eto'o's agent Claudio Vigorelli said that the Blues were one of three clubs in the chase for the 32-year-old Cameroon international, according to ESPN UK.
Delaney notes that if a deal can not be reached for either Eto'o or Rooney, a potential third target may be Galatasaray's Burak Yilmaz, although Delaney states that no contact has been made with the Turkish star.
There is also a bit of news surrounding a potentially outgoing forward at Stamford Bridge.
Roma has an opening at the position after Pablo Osvaldo turned in the Eternal City club for Southampton on Monday.
One has to believe that if Ba is let go, Chelsea will have to bring in another forward to replace him first.
Perrin reports that both clubs are scheduled to have talks with the Anzhi forward, who is available for a relatively cheap £5 million.
The main hold up in any proposed Eto'o deal will be his wages as he is currently making over £300,000 per week in Russia.
Turning our attention to a brand new transfer target of the Blues is John Richardson of The Express, who is reporting that Chelsea, along with Manchester City and Arsenal are in a fight to sign PSV Eindhoven phenom Zakaria Bakkali.
Bakkali has already become the youngest player to score a hat-trick in the Eredivisie this season at the age of 17, and the interest in his talents from the big clubs of Europe is beginning to find momentum.
Bakkali and PSV will take on AC Milan in the UEFA Champions League play-off round on Tuesday, but it is unsure if he will play due to a small groin tear he suffered on international duty, according to the Sky Sports match preview.
The bid for Rooney is expected to be £40 million, and the Blues may offer Rooney £300,000 per week to lure him away from United.
If the final approach for Rooney fails, Borussia Dortmund's Robert Lewandowski could be targeted by the West London club.
Jefferson also reports that the Polish forward has had his wages tripled by Dortmund to make sure he sees out the remainder of his contract, which runs out at the end of the season, in the Bundesliga.
Another potential option at the forward position according to Metro's Jamie Sanderson could be Porto's Jackson Martinez, who could potentially be a £25 million target of the Blues.
