Chelsea will surely be looking to invest in some top end defenders considering their newly implemented policy that promotes youngsters. With Terry just turning 34, with Luiz close to a possible transfer and with Ivanovic being two months short of reaching 30 years of age, the Blues could be in the market for one or two promising footballers with strong defensive qualities.

According to Metro, Porto’s Eliaquim Mangala has recently grabbed Mourinho’s attention. Even if the London based club has not yet made their intentions to place a bid for the 22 year old Frenchman clear, all the signs point to a possible deal. The French international who came to Portugal in 2011 is expecting an increase in his salary, as the Portuguese side have been talking about awarding him a raise to fend off interest from other teams.

Mangala who has also played for Standard Liege is one of Europe’s most sought after defenders. Chelsea is not the only Premier League team interested in getting his signature. City and Manchester United also look keen on luring the 22 year old to the UK. Porto’s central defender is valued at £17.5million but is still under contract until 2016. Even so, the Frenchman has a £40 million release clause which is pretty reasonable for a club with Chelsea’s financial muscle. He would be the perfect successor for Terry who has not yet received an extension to his contract which is due to finish at the end of the season. He would also be a perfect fit for the Blues’ defensive line to complement the more offensive qualities of Luiz and Ivanovic.

The Frenchman’s market value is constantly increasing. With Didier Deschamps calling him up to represent his country and with the World Cup fast approaching, Mangala’s price will surely shoot up.  A transfer during the winter period would be a great achievement for Chelsea who are definitely looking for talent but also for a young player that can grow and improve by performing in the Premier League.
