When it comes to the case of Romelu Lukaku, no logic appears to be in-situ in West London.
Sami Mokbel of the Daily Mail reports that the Stamford Bridge club hope Lukaku has a fine World Cup in the summer, hoping to swell his value and reputation further:
Jose Mourinho is prepared to let Romelu Lukaku leave Stamford Bridge ahead of next season as he looks to revamp his forward line. Aston Villa striker Christian Benteke's ruptured achilles means Lukaku is almost certain to be Belgium's first-choice striker in this summer's World Cup.
And while Chelsea already value the 20-year-old striker at in-excess of £20million there is a sense at Stamford Bridge that his price tag will inflate significantly if he has a productive tournament in Brazil.
It is amazing to think that the man-mountain Belgian international is only just out of his teenage years. The 20-year-old has had two full seasons plying his trade in the Premier League, after two very successful stints at West Brom and Everton.
In his 35 appearances for the Hawthorns club last season, he hit a very credible 17 goals.
This year, in what has been a step up in class playing at Goodison Park, he has managed to score 13 times in 25 games.
He appears to be the real deal: a youthful and physical talent in the mould of Didier Drogba, universally accepted as a future world star.
Except by Mourinho, who it appears wants to sell him to the highest bidder.
It is questionable why Mourinho would consider selling such a talent when his striking options are positively dire.
Why is the Chelsea manager so repelled at the idea of Lukaku being a part of his squad when the likes of Samual Eto'o, Fernando Torres and Demba Ba seem ill-equipped for the rigours of Premier League football?
In fact, WhoScored.com indicates that these three strikers have 15 domestic league goals between them this year. In a Chelsea shirt, it is arguable to say that Lukaku would have more than this total already with Eden Hazard and Oscar feeding him.
Even Gary Lineker recently spoke on the matter, taking to his Twitter account to question Mourinho's judgement:
Here is a player with supreme talent, who in his two years in a Blues shirt had won the Champions League and the Europa League, but did not fit the long-term vision of Mourinho on his return to Stamford Bridge.
This fact is undeniable and logical. However, the selling of Lukaku would be negligent and ill-advised.
Quite clearly, Mourinho will go and spend some of Roman Abramovich's vast wealth in the summer on a world-class striker, but to ignore a player already at his club with a vast amount of potential shows his mentality and his personal failing.
Mourinho has always had faith in older, experienced players and has long ignored youth when building his previous squads at his former clubs.
Lukaku is perfect for Chelsea at present and for the formation that they play. His mobility and Drogba-like energy make him an excellent candidate for Mourinho's preferred system.
And even if The Special One did not see him as a first choice for next season, he would be the correct striker to rotate in and out of the starting line-up as his new players bed in for the 2014-15 season.
Mourinho showed on Tuesday why he is such a revered manager, as he conducted his orchestra to play to precision and knock out Paris Saint-Germain from the Champions League.
However, the way the Portuguese manager has handled Lukaku has shown his own weaknesses and stubborn attitude.
To forsake Lukaku will ultimately see Chelsea release a player who could have led their line successfully for a decade. He could have been a player who remained at Stamford Bridge a lot longer than his current manager might.
Ultimately, the Belgian will go elsewhere and be a huge success, and Mourinho's failing will be another manager's story of development and triumph.
