Chelsea planning to sign 'two or three players' this summer says Jose Mourinho

Chelsea manager Jose Mourinho says the club are preparing to sign as many as three players during the summer transfer window after revealing his plans for the off-season.

The Blues have made one addition in the form of Brazilian youngster Nathan but the 19-year-old is not expected to figure in the first team during the coming season.

After cruising to the league title and finishing eight points ahead of second place Manchester City, Chelsea have naturally been linked with a host of players including Radamel Falcao, Christian Benteke and Moussa Sissoko.

Mourinho is regarded as one of the shrewdest operators in the transfer market having helped Chelsea offset major money signings with the sales of key players including Kevin de Bruyne and Andre Schurrle.

Any significant signings this summer will again be followed by a high-profile departure as Chelsea continue to adhere to the Premier League and Uefa's financial fair play regulations but Mourinho predicts subtle changes to his squad rather than a deluge of spending.

"It will be difficult to find players to go straight into the team," he told The Sunday Times.

"Because it's not easy to find a better striker than Diego [Costa], a better keeper than [Thibaut] Courtois, a better midfield player than [Nemanja] Matic or [Cesc] Fabregas.

"This season is about improving the squad, bringing players to make us more consistent, so we don't go through difficult periods like last season when we had crucial injuries. We have to try and protect that situation by adding two or three players."

Despite Petr Cech, Loic Remy and Kurt Zouma being subject to speculation regarding their future at Chelsea, Didier Drogba is the only confirmed departure after coming to the end of his contract.

"We will be better," Mourinho added. "I don't see our team losing players. I don't see our team losing our qualities, especially our mental, emotional approach to matches, to the season, to the competition."
