Filipe Luis committed to Chelsea despite Atletico Madrid transfer links

Chelsea defender Filipe Luis has claimed he is not currently concerned by speculation linking him with a move away from Stamford Bridge and insists that he is fully focused on ensuring that the club finish strongly in their pursuit of a first Premier League title since 2010.

Luis, a La Liga winner and Champions League finalist with Atletico Madrid last season, joined Chelsea in a £15.8m deal in July 2014 just a matter of days after teammate Diego Costa had completed his own high-profile switch to West London.

Costa has had a major impact during his first season in English football with a healthy return of 19 goals in all competitions, yet Luis by contrast has failed to establish himself as first-choice left-back under Jose Mourinho, leading to reports this week suggesting that the 29-year-old could be used as a makeweight as Chelsea seek to negotiate a deal for another of Atletico's prized assets in Spain international Koke.

While a return to the Vicente Calderon could presumably appeal to Luis if he is unable to win favour ahead of the ever reliable Cesar Azpilicueta over the coming weeks, for now the Brazilian remains focused on the task at hand and seems eager to make a success of his time at Chelsea despite a lack of regular starts.

"When I arrived here in Chelsea, I signed a three-year contract, which I want to fulfil," he was quoted as saying by the London Evening Standard. "The team is in a great period, the team was champion in the League Cup, has the possibility of being champion of the Premier League, which is the most important to me.

"I do not think about the speculation, nothing of it. My head is completely focused on Chelsea for the season finale. I know people can talk a lot and will talk a lot, but my head is prepared for this end to season which is very important both in Chelsea, as the national team."

Chelsea, who were knocked out of the Champions League on away goals at the last 16 stage earlier this week after a controversial 2-2 draw against Paris Saint-Germain, return to domestic action on Sunday (March 22) with a trip to Hull City.

Following Manchester City's dreadful 1-0 defeat to struggling Burnley, Mourinho's side currently boast a six-point advantage over their nearest title challengers and also have a game-in-hand to be played next month.

As has been the case all too often this season though, all eyes are likely to be focused upon referee Michael Oliver at the KC Stadium after Chelsea this week appeared to lend support to their manager's theory of an ongoing campaign against his team by bemoaning the 'abnormally low' number of penalties given in their favour over recent months.

Costa and Branslav Ivanovic both had appeals firmly rejected by Mike Dean during their last league outing at home to Southampton, with the former tumbling under the challenge of Jose Fonte and Ivanovic clearly clipped by Dusan Tadic.

Oliver was widely praised for his handling of Arsenal's FA Cup quarter-final victory over Manchester United at Old Trafford earlier this month, a match in which he dismissed Angel di Maria after the former Real Madrid playmaker grabbed hold of him in frustration at being cautioned for simulation, and is unlikely to be swayed by such external pressure.
