Cape Town - Former Chelsea defender Paulo Ferreira has praised the work of Spanish pair Diego Costa and Cesc Fabregas since they arrived at Chelsea in the summer.
"At the moment Chelsea is doing really well and I am very happy for that," Ferreira said on chelseafc.com.
"I think they can be champions, it will still not be easy, it will be a long and hard season, but I am really pleased with how the team is doing.
"The new players that came have lots of quality and the important thing is they have adapted easily. Diego Costa just arrived, it’s his first season and he is scoring goals. Cesc Fabregas knows the Premier League really well and is a top player, they came and brought extra quality to the team.
"It helps Diego Costa to have some Brazilian players in the team to help him settle, to tell him how the league works, and I think that’s important.
"When you spend money on top players, you want to see them arrive and succeed, and it’s what we’ve seen from him. I am really happy for him because he is doing really well. And I am sure the manager is really happy. The supporters want to see him scoring goals too and he’s doing that."
Ferreira retired at the end of the 2012/13 campaign after making over 210 appearances for the Blues.
Costa has already netted 10 goals for Chelsea this season and continues to revel in his partnership with Fabregas, who has provided no fewer than 9 assists to the team's cause this season.
Chelsea have a four point lead at the top of the English Premiership and are odds-on favourites to wrestle the title from Manchester City this season.
