Chelsea welcome Manchester United to Stamford Bridge today in an exciting Premier League clash.The Blues will look to go four points clear at the top and extend their unbeaten run in all competitions to 11 games. Confidence is high in the camp, particularly after the 4-0 rout of Juventus in the Champions League on Tuesday.

But a lack of first-team opportunities saw him go out on loan the following year.After re-establishing himself at Benfica, the Serb returned to Stamford Bridge in January 2013. He quickly became a mainstay in their midfield, winning three titles over the next four and a half seasons.Manchester United came calling for his services in 2017, and Matic was reunited with his former Chelsea boss Jose Mourinho.Manchester United@ManUtd#MUFC is delighted to announce the signing of Nemanja Matic from Chelsea on a three-year contract. manutd.com/en/News-And-Fe… #MaticIsRed8:31 AM · Jul 31, 20174911642343#MUFC is delighted to announce the signing of Nemanja Matic from Chelsea on a three-year contract. manutd.com/en/News-And-Fe… #MaticIsRed https://t.co/vbl8kSLbEOHe has been a key player for them since then, but hasn't won a trophy with United yet.#4 Juan MataThe Spaniard's 2012/13 season with Chelsea is still fondly remembered.Signed from Valencia in August 2011, Juan Mata was an instant hit at Stamford Bridge.
