Chelsea boss Jose Mourinho says the Blues will be even stronger next season but without the need to invest heavily during the summer transfer window.
Chelsea dominated the English Premier League but suffered a surprise exit at the hands of Paris Saint-Germain in the Champions League.
But the Portuguese is convinced that no "big investments" are required to strengthen his squad.
"Next season will be even better than this season and without big investments, because we don't want to do that because we are happy with the players," Mourinho is quoted as saying by Sky Sports.
"Our group is top. The qualities are good. The most important thing in the market for us is not to lose players, I want to keep my players.
"Part of that when I say two, three players is to improve a little bit the squad.
"I am not saying the team because how can I find a better striker that Diego Costa, how can I find a better midfield player than [Nemanja] Matic, how can I find a better right-back than (Branislav) Ivanovic?"
