Video: How did Chelsea fare in the transfer market?

Having finished third in the Premier League last season, there were clear areas of the pitch where Chelsea needed to improve this summer.

Manager Jose Mourinho has looked to address those positions, spending big money to bring the likes of Diego Costa, Cesc Fabregas and Filipe Luis to the club.

There has also been something of a clear-out at Stamford Bridge, with no fewer than 18 players leaving temporarily or permanently, including club stalwarts Frank Lampard and Ashley Cole.
