Griezmann has been linked with a move to ChelseaReuters

Jose Mourinho has insisted Diego Costa is staying at Chelsea while ruling out the signing of Antoine Griezmann, after recent reports claimed the Portuguese boss had earmarked the signing of the Atletico Madrid forward as a priority for the summer transfer window.

The 24-year-old France international was linked with a number of Premier League clubs in recent seasons, including Arsenal, Tottenham and Liverpool, but in summer 2014 he opted instead to move to the Vicente Calderon after Diego Simeone's side agreed to match his €30m (£22m, $34m) release clause at Real Sociedad.

And after Griezmann showed impressive development during the 2014-2015 season, there have been a number of reports in recent weeks claiming Mourinho is considering triggering his £43m clause at the Calderon as he did last summer to sign Costa to partner the France star with the Spaniard in the Blues' attack.

Griezmann has scored 25 goals in his debut campaign under Simeone to cope with Costa's departure and become the third top scorer in La Liga, just behind Cristiano Ronaldo and Lionel Messi, despite playing behind Mario Mandzukic.

But Mourinho has claimed that even though the France international is proving to be a "great player" he is not in his summer transfer plans.

"Griezmann is a great forward but he is not one of our objectives to reinforce the squad for the coming season. We're not interested," he said to Marca.

At the same time, the Portuguese boss has assured Costa "will not leave" Stamford Bridge, insisting he is happy at Chelsea.

"I see him happy at the training sessions. He is always laughing and is involved in the dressing room. I think he's enjoying every minute at Chelsea. I can assure you that he will not leave Chelsea this summer, that's for sure," Mourinho said.

On Tuesday 2 June, the striker himself had already denied reports in Spain claiming he wants to return to Atletico Madrid just one season after moving from the Vicente Calderon stadium to Stamford Bridge for £32m.

"[It is] quite a simple answer. It's always a bit more difficult in the first season to adapt, but I have no reason to leave this place, I love it, the fans love me and I want to stay," Costa said.
