Samuel Eto'o is a top, top striker. Of that I have no doubt.
Fernando Torres hasn't exactly set the world on fire at Chelsea but few can substantially doubt his credentials as a forward.
However, both didn't perform during yesterday's surprise 1-0 defeat away at Everton, and what Mourinho needed was someone he has in fact loaned to the Merseysiders: Romelu Lukaku.
Of course, it would perhaps be stretching it to say that if Lukaku had played yesterday Chelsea would have won. But they damn sure looked like they needed him.
The young forward possesses such brute power, akin to Blues legend Didier Drogba, and it seemed Mourinho's men clearly lacked that on Saturday evening.
Granted during the second half Chelsea did look dangerous and thus looked the more likely of scoring the next goal, but time after time, the ball was played up to Eto'o and it didn't stick. His lack of holding the ball up allowed Everton to regroup and they were then able to stifle many dangerous opportunities.
If Lukaku was there, he would have posed a different problem for the Everton centre-halves. Not only is he strong but he is quick too, and can lose an opponent with his deft movement. He reads the game so well for someone still at the tender age of 20.
In that type of encounter, where you know you are going to be put under immense pressure not just from your opponents but also from a vociferous home support, it is often a different option that can unlock the door. Lukaku is that option.
Torres made little impact when he was introduced as a minute substitute. Had that been Lukaku coming off the bench, Chelsea's chances of grabbing a goal would have improved.
In the dying stages of a match, the last thing you want is someone that carries both a significant aerial threat and a lethal goal threat. 17 goals in 20 starts for a West Brom side who finished eighth in the Premier League suggests a real potency in front of goal, and in truth Chelsea haven't really had that since Drogba left Stamford Bridge. They definitely missed that at Goodison.
The defeat yesterday cast doubt in Mourinho's decision to let Lukaku leave on loan. Surely he would have started with Eto'o anyway but the Portuguese manager might well be ruing his choice to let the Belgian gain experience elsewhere.
It remains to be seen whether it was a good decision or a bad one for Chelsea, but so far, Mourinho must be thinking letting Lukaku go to Everton was truly a deadline day disaster.
