The future of Chelsea's current strikeforce looks bleak after José Mourinho confirmed he intends to revamp his side's front-line, as well as instil fight and focus into his other attacking talents, for an assault on the title next season.

Mourinho conceded his team's hopes of winning the Premier League were effectively over after Saturday's defeat at Crystal Palace, his first by a newly promoted club and a result that handed the initiative to Liverpool and Manchester City in the title race. The Portuguese praised the effort and commitment of his defence in the 1-0 defeat but was critical of others for "disappearing" in a game they might have anticipated winning. He had confirmed straight after the match that his side had lacked "balls" at Selhurst Park.

The main ramifications will be felt by the forward line, with Chelsea expected to try to prise the Brazil-born Spain forward Diego Costa from Atlético Madrid. While Samuel Eto'o will be out of contract, the futures of Demba Ba, Fernando Torres and even Romelu Lukaku will then come under scrutiny dependent upon what interest is generated.

"I don't think it's the moment to speak about next season and the market but it's clear to everybody that Chelsea next year wants to bring a striker," said Mourinho. "What's the future for the other strikers? The ones who are staying are competing with the striker we are bringing [in]. And normally, at the end of the season, players that are not playing a lot or players who are not happy may prefer a change. That is also part of the market. We want to improve the team and the players and make some surgical movements in the transfer window."
