Chelsea fans must be hoping Holland manager Louis van Gaal keeps his opinions to himself after he was quoted this week by Turkish newspaper Vatan suggesting Galatasaray's Wesley Sneijder is on the Blues' radar for a January transfer.
Three years ago, a move for the Dutch midfielder would have been shrewd business for most European clubs, not just Chelsea. But now the 29-year-old's presence alone would cause more problems than it would solve for Mourinho.
Back in 2010, Sneijder had not long inspired Inter Milan to success in the Champions League, adding to the Coppa Italia and Serie A as the Nerazzurri made history by claiming an unprecedented treble.
He was also an influential presence as Holland marched to the World Cup final in South Africa, where they were eventually overcome by Spain.
In 2013, Sneijder is a far different prospect, though. He hasn't been at his very best since that memorable campaign, with injury and pay disputes with Inter, one of the many factors that have seen him struggle to make a similar impact.
He moved to Galatasaray as a result this January and while there have been moments of brilliance during his time in Turkey, he has the look of a player whose best days are long since passed.
It must be a concern for van Gaal as he looks to build his Holland team ahead of next summer's World Cup in Brazil, yet it would be a bigger concern were Chelsea to undergo an attempt at reviving his career.
Beside the legitimate doubts over his ability to consistently perform at the highest level, the reality where Sneijder is concerned is Chelsea have more talented players in his position now—players with youth on their side and who fit the club's ethos.
It's a wealthy pool of talent Mourinho has at his disposal, too. It's one that brings him considerable depth with names such as Juan Mata, Oscar, Eden Hazard, Andre Schurrle, Willian and Kevin De Bruyne for him to choose from.
Throwing Sneijder into the equation will go against everything the Portuguese and the club are trying to build. Chelsea have had their "Galacticos" moment and with their recruitment policy now focused on bringing in future stars as opposed to established names, they've conceded it didn't work.
So why return to it?
It's how Chelsea work best, bringing in players who are highly-desired, yet haven't scaled the heights of Champions League finals just yet.
Didier Drogba, Arjen Robben, Petr Cech—the list in the past decade has been impressive. The strategy was signing players whose star was still rising and it's a policy that has since been revisited at Stamford Bridge, paying dividends.
Sneijder is very much the antithesis of that. He remains talented, sure, but he isn't what Chelsea need, particularly when the Blues' squad needs strengthening elsewhere.
Signing Sneijder would congest an already overloaded attacking midfield. It will throw out all the good work Chelsea have put in to restructure the club in recent seasons. It would set them down a dangerous path and we know how that has ended in the past.
