The Portuguese has reiterated the need for the Blues to bolster their attacking options with Atletico Madrid striker Diego Costa set to move to Stamford Bridge this summer
Jose Mourinho has confirmed Chelsea will sign a striker this summer as the club look to bounce back from a trophyless season.
Goal revealed a week ago that Atletico Madrid striker Diego Costa has agreed to move to Stamford Bridge at the end of the season in a deal worth £35 million.

There was disappointment in Europe, too, with Mourinho's men suffering a semi-final exit at the hands of Atletico and Costa in the Champions League.
The Portuguese has not been shy in criticising his current strikers in public, with Samuel Eto'o, Fernando Torres and Demba Ba netting just 18 league goals between them this season.
And in his pre-match press conference on Friday, Mourinho reiterated Chelsea's need to bolster their attacking options.
"The striker is something we are speaking about for a long, long time," he said.
"In December and January, when all of you [the press] were asking why we were not bringing a striker, I was clear in saying it's something we were working on, that we were preparing the long-term future and not just an immediate solution.
"It's normal that we're going to bring a striker now. We have good strikers, good players, but it's the normal evolution of the team.
"Everyone wants the summer transfer window to improve and one area that we want to improve is the strikers' position."
