After a rocky start to their Premier League defence; Chelsea have brought in FC Barcelona forward Pedro to try and fire the Blues towards some quick-fire wins after a tricky start to the 2015-16 season.
Having conceded seven goals in their opening three league games, including the 3-0 hammering at Manchester City, the Blues need to strengthen their defence upon the close of the transfer window though,. as the defending champions are already playing catch up with their nearest title rivals.
Manager Jose Mourinho is eager to bring England centre-half John Stones to Stamford Bridge from Everton, although the Toffees have already rejected three bids of £20m, £25m and £30m respectively for the defender already this summer.
The 21-year-old, who has four international caps, has handed in a transfer request which could help push the long-running saga along though.
