Chelsea came up short in their quest to win the Premier League and Champions League last season, prompting manager Jose Mourinho to embark on a huge summer spending spree. 'The Special One' forked out £100m to bring the likes of Filipe Luis, Cesc Fabregas, Diego Costa, Didier Drogba and Loic Remy to Stamford Bridge, whilst also allowing the likes of Ashley Cole, David Luiz, Frank Lampard and Samuel Eto'o to leave.
So far, it's worked fantastically. The Blues are top of the Premier League after a superb start to the season, which has seen Mourinho's men pick up 19 points from the first seven games having racked up six wins and one draw. The only blot was that draw at Manchester City, where the aforementioned Lampard scored a late equaliser for City against the club where he became a legend.
Whilst covering the Slovakia vs Spain game for Sky Sports tonight, Lampard revealed that whilst he's been impressed with his replacement Fabregas, it's Diego Costa who has impressed him the most for Chelsea this season. Costa, 26, arrived from Atletico Madrid for £32m this summer having hit 36 goals for the La Liga champions last season, and his form has continued into the Premier League with nine goals in his first seven games - and Lampard acknowledged just how good the Spanish international is.
"I've watched their games from afar and we've played against them. It's no surprise for me with either of them; Cesc Fabregas, I played against him at Arsenal, he knows the Premier League and is a top, world-class player. And we watched Diego Costa before we played Atletico Madrid in the Champions League semi-final last year - we watched the video and we probably could have sat there for about three hours and watched his running and goals and everything he was doing, and I thought he was some player and Chelsea have signed that player."
