When Chelsea striker Romelu Lukaku was loaned out to Everton on transfer deadline day, fans were left wondering why.
Their questions have only grown louder as the big Belgian continues to find the back of the net for club and country whilst Chelsea's senior strikers struggle.
Lukaku has scored four Premier League goals in just two starts for Everton this season, inspiring the Merseysiders to to a healthy seventh place in the Premier League.
Luakau's tally of four is, unbelievably, four more than Fernando Torres, Demba Ba and Samuel Eto'o have mustered up between them for Chelsea.
Another brace for Belgium in the World Cup qualifier against Croatia compounded what seems like a terrible error in judgement for Jose Mourinho.
But the criticism Mourinho is fronting now is for a greater purpose, one likely to reap fantastic benefits in the not-too-distant future.
Lukaku was terrific for West Brom last season and many thought he was ready for the big time at Chelsea. But the pressure to perform at Stamford Bridge, for the title contenders, in the Champions League, is much greater than it is at the Hawthorns.
That pressure may have got to the 20-year-old and the fact that he would be rotated with Torres, Eto'o and Ba means he would never find the rhythm needed to achieve his potent form.
He is far from the finished article either. There is still a distinct lack of goals scored when he meets more experienced defenders from better sides.
Another season away from the club and, all being well with his fitness, he will likely play over 30 games for Everton in the Premier League and improve dramatically.
Chelsea's trio of striker misfits will be another year older and, with Ba likely to leave, a slot will open up - Lukaku will slide in to the team perfectly.
He looks the finished article and may well out score all of Chelsea's strikers whilst at Everton, but that doesn't mean he would have done the same at Stamford Bridge.
By loaning him out, Mourinho has made sure that his development isn't stunted by his big squad of senior players.
Lukaku will return to Chelsea eventually and will be a better player for his loan spells.
Mourinho may have missed out on the player's talents this season and is being criticised for it, but his reward is the safeguarding of Lukaku's rise to the top of world football - something his potential has always promised.
It's a sign that The Special One may actually be in it for the long haul at Chelsea.
