Chelsea FC are determined to sign Paris Saint-Germain defender Marquinhos this winter in exchange for excess of A?40million to reinvigorate their defence that has let in second most number of goals in the Premier League this season.

The Brazilian centre-back has established himself as one of the most promising talents in and around Europe, having become a regular fixture at Parc des Princes. Accordingly, Barcelona and Chelsea FC have already locked horns with each other to secure his services.

With John Terry struggling to reciprocate his form of last season, the Stamford Bridge club can be deemed to be in dire need of defensive reinforcements, despite adding Papy Djilobodji to their roster in the summer. Marquinhos could be the ideal choice to replace the Chelsea skipper in the long term given his undoubted prowess.

The 21-year-old has time and again voiced his frustration over playing second fiddle to David Luiz and Thiago Silva either directly or through his agent, Giuliano Bertolucci, who told Le Parisien last winter that his client could be open to a move.

a Marquinhos wants to become the best defender in the world,a his agent claimed. a He respects the decisions of the coach, Laurent Blanc, buts wants to play more than anything and not spend so much time on the bench.a

Chelsea FC failed in their attempts to land the Brazil international twice last summer, having seen their A?25.7million and A?40.4million bids turned down by the French club. However, Roman Abramovich may break the record for the most expensive defensive transfer when the transfer window opens.
