Jose Mourinho never seems to be fazed by the prospect of losing one of his players to a Premier League rival. After all, it was only in January of 2014 when he opted to offload Spanish playmaker Juan Mata to Manchester United.
Mata, who was voted the club's Player of the Year twice in succession before Mourinho's return to the club, was shipped off to Manchester for a mega fee. Mourinho and Chelsea quickly moved on.
Cech on his way?
And, with a summer transfer window on the horizon, perhaps the Blues boss will consider moving on another one of his stars to a rival. One man that looks destined to depart the Bridge is shot-stopper Petr Cech.
Cech, despite starring in the Capital One Cup final this past weekend, has endured a tricky season at the club after the arrival of Belgian international Thibaut Courtois. The man who spent three years on loan at La Liga outfit Atletico Madrid has adapted to English soil extremely well, leaving Cech in limbo.
In fact, Mourinho has admitted that his 32-year-old 'keeper could be on his way out in the next transfer window, but it will be for huge money.
On the player's situation, the Chelsea chief told reporters: "I don't think Petr is a guy to be persuaded. He doesn't let anyone persuade him.
"I think he's very mature making what he feels is the best decision for him and his future. I will just wait, wishing his decision is to stay. That's my desire. I would like him very, very much to stay.
"But I don't waste my time trying to persuade him because it's just his decision. If he tells me he wants to leave I will tell him my opinion, that he is one of the three best goalkeepers in the world, so huge money."
So, then, big money could see Cech leave the club, but where will he go? Well, one club that have been linked with his services are Arsenal.
Arsene Wenger may well have the duo of David Ospina and Wojciech Szczesny at his disposal, but many still see the goalkeeping department at the club as a weakness.
In fact, the club's former 'keeper Jens Lehmann recently told the Alan Brazil Sports Breakfast show: “Courtois is probably the best [young] talent around and he has done really great so far, but in tight games he still has to prove he is up to the challenge of what Petr Cech has done.
“He [Cech] is getting to the best age for a goalkeeper. I have experienced it myself, when all of a sudden physique comes together with experience. The best years are still ahead of him.”
Cech would prove an incredible signing for Chelsea. And Lehmann's suggestion that the goalkeeper's best years are still in front of him may actually not be that far-fetched. Yes, he is 32, but there's no reason why he doesn't have a decade of football at the highest level ahead of him.
Think about this: Manchester United sign Edwin van der Sar when he was 34-years-old. He retired as a hero at the Theatre of Dreams after remarkable success at the club. In fact, he was arguably the club's best 'keeper since the great Peter Schmeichel.
Cech still has so much to offer, and he'd prove the defensive leader that Arsenal so desperately need.
Don't do it, Jose
And that's why Mourinho must not sell to the north London club. Time-and-time again, the Blues boss has insisted that Cech is one of the top three goalkeepers in world football. Why, then, would he want his world-class player starring at one of his league rivals?
Cech, who earns a reported £100,000-a-week at Stamford Bridge, will surely have to move on this summer, but Mourinho must make sure it's not to Arsenal. He'd be giving Wenger and Co. a major platform to build on as they go in search of toppling the Blues in the long run.
Arsenal are certainly growing, but they still have vulnerabilities at the back, so Mourinho shouldn't play his part in helping them sort that out. Even if the Gunners come in for the 'keeper, on this occasion, the Chelsea hierarchy should look the other way.
The player's good enough to star at near enough any side in world football, so it's crucial that Mourinho moves him abroad ahead of the 2015/16.
