In recent weeks the largest criticism aimed his way relates to the decision to loan the player out to Everton, who is now scoring more goals than his current striking line-up put together.
The decision to allow Belgian international Romelu Lukaku to spend this season on loan at Goodison Park is starting to receive more and more criticism by the day - yet Mourinho remains unabashed.
At the moment, Chelsea have three strikers, none of which look like leading the line of a Premier League title-winning team.
Fernando Torres is still sulking left, right and centre while Demba Ba puts on a brave performance, but he can’t find the back of the net.
As for Samuel Eto’o, he looks even older than the already aged 32-years-old, and years playing in Russia for Anzhi seemed to have rendered him impotent in front of goal.
Perhaps Mourinho went for the wrong former Inter Milan colleague - perhaps he should go for another one in January.
Diego Milito had one of the best seasons of his career at Inter after being signed from Genoa by Mourinho in the summer of 2009.
His goal return of an incredible 30 goals in 52 appearances saw him claim numerous accolades - including UEFA Player of the Year - as well as a treble with the Nerazzuri.
But since then, he has suffered with injuries.
This season he has only featured twice, scoring once, and his current deal expires at the end of the season.
That means he is free to sign with any club for free in January - without the explicit permission of Inter Milan to talk to the prospective new employers.
On paper it would be a great deal, but again, not the solution to Chelsea’s problem.
Milito is currently out with a thigh injury and is already 34-years-old. Signing him before next summer, for a reduced fee in January, may be an option but he is not getting any younger.
Chelsea would be left with another Eto’o - a shadow of a once world beating centre-forward, clawing at his former glory.
What they need is a similar goal-getter, with hunger, desire and youth, to breathe some life into the vapid strike force at Chelsea.
I think I know a player who plays for Everton … oh wait a minute…
Do you think Milito would be a good signing?
