Chelsea defender Ricardo Carvalho admits his side need to improve before the start of the new season.
The 32-year-old made his first appearance in pre-season on Sunday after being given an extended break after his exploits with Portugal in the World Cup.
Chelsea began pre-season with a 1-0 win over Crystal Palace before losing 3-1 to Ajax and 2-1 to Eintracht Frankfurt.
Although the outcomes of pre-season games are often seen as meaningless, Carvalho says Chelsea need to start winning matches and playing better in friendlies.
He told the club’s official website: “I am not sure if Frankfurt were fitter, both teams played more or less at the same level, I think we could play better but so could they, and in the end they were a little bit lucky with the penalty.
“For us now the next game is on Wednesday, and I look forward to it and improving my condition, and for the team it is time to get results, to start to win and to play better.”
Patrick Ochs scored the opening goal of the game in Frankfurt’s 2-1 win over Chelsea before Halil Altintop cancelled out Frank Lampard’s second-half equaliser late on.
Carvalho added: “I think we could play much better but the pitch was a little bit difficult, you could feel it during the game, and we made a mistake with the penalty and they scored, so I think we should have had a draw at least.”
