Antonio Conte has received a boost in his hopes to keep Diego Costa at Chelsea ahead of next season after Atletico Madrid announce the signing of Kevin Gameiro from Sevilla. The La Liga clubs have failed to disclose the terms of the deal but reports in Spain claim that Los Colchoneros have paid €32m (£27m, $35.7m) plus add-ons to secure the French striker, who has signed a four-year deal at the Vicente Calderon.

Atletico Madrid had earmarked the signing of a proven top scorer as a priority for the current transfer window, having previously signed Nico Gaitan, right-back Sime Vrsaljko and promising winger Diogo Jota to strengthen other areas.

Costa was said to be the number one target after he only left the Vicente Calderon to join Chelsea in the summer of 2014 for around €40m. Yet, Los Colchoneros have also been linked with Gameiro in recent days, due to the Blues' reluctance to negotiate the departure of the Spanish striker despite having reportedly launch an offer worth €60m to lure him back to La Liga.

Earlier this week Spanish publication AS reported that the Chelsea striker had made a phone-call to Simeone to ask the manager to wait for him and put the move for Gameiro on hold.

Costa later added more fuel to the speculations after posting a message on his Instagram account, where he appeared to say goodbye to his Chelsea teammates after not being used in the friendly against Liverpool.

However, on Friday it was said that Simeone was growing tired of waiting for Costa and had asked the club board to complete the signing of a number nine before the 6 August.

Later local publication El Diario de Sevilla broke that Atletico and Sevilla had agreed a deal in principle for French striker to be the new number nine of Los Colchoneros next season.

Atletico have now made the news official after the 27-year-old agreed to commit his future to the Vicente Calderon for the next four campaigns.

"Atlético de Madrid and Sevilla FC have reached an agreement for the transfer of Kevin Gameiro to our club. The striker, who will sign for four seasons, will travel to Madrid this evening," Atletico confirmed through an official statement. "The transfer is contingent to the French player successfully undergoing the medical examination."

The clubs have failed to disclose the terms of the deal but El Diario de Sevilla reports that Atletico have paid a fee amount of €32m, which could rise to €36m on add-ons. Furthermore, the deal is also expected to include Luciano Vietto's move on loan to Sevilla, linking €4m extra to an operation that in total could cost Atletico up to €41m.
