8 Chelsea Flops Who Made It Big Elsewhere

8. Felipe Luis

Felipe Luis came with a massive reputation from his time at Atletico Madrid. He was at the heart of the solid defence which laid the foundation of the side's improbable league success in 2014, and was also subsequently voted as the best defender in La Liga alongside Miranda and Sergio Ramos.

Chelsea soon came calling and acquired his services for a fee that appeared to be a steal at the time, but the Brazilian couldn't displace Cesar Azpilicueta.

With only 15 appearances in the Premier League, the full-back failed to nail down a starting spot. He couldn't find his way into Jose Mourinho's plans and remained an understudy to the aforesaid Spaniard. His only meaningful involvement throughout the campaign was a brilliantly executed free-kick against Derby County in the League Cup.

This lack of first-team opportunities prompted him to duly return to the Spanish capital in 2015, after just a year at the Stamford Bridge, costing about five million less than what the Blues bought him for. However, Luis instantly regained his position in Atletico's set-up and went on to prove himself as a fine left-back once again.
