The Portuguese manager failed in his attempt to lure Manchester United and England forward Wayne Rooney to London over the summer, and went in the direction of Samuel Eto’o, which has worked out to an extent.
But looking at the squad, Chelsea is missing a key man up front in what might be the last piece of the title-winning puzzle.
Demba Ba and Fernando Torres have been squad players for the majority of the season, chipping in goals here and there, but nobody seems to have become a force.
With that in mind, Mourinho is looking forward to the summer to bolster his options.
Eto’o will be out of contract soon, and since Mourinho is not convinced even by loan star Romelu Lukaku, Chelsea could see an influx of names up front.
A new name emerging is Atletico Madrid’s star forward Diego Costa, who has been ripping La Liga defenses to shreds this campaign.
In 30 league games, the Brazilian striker has 25 goals and three assists. And in the Champions league, he’s hit the net seven times.
At 25, Costa could be a long-term solution, too.
But Chelsea will face competition causing the price tag to go up. That has never been a big deterrent to the free-spending club.
