Frank Lampard has made 777 appearances for Chelsea, netting 233 goals, but can anyone fill the void he'd inevitably leave should he seek pastures new in the summer? I think the three players below could be the best possible candidates for the job.
Marouane Felliaini - Everton & Belgium
The midfielder has made quite a start to the season and could be seen as the driving force behind Everton's success, scoring eight goals.
Although this isn't a staggering amount, his ability to trouble even the league's best defenders in the air is impressive, and his timing and touch means he is able to pluck the ball out the air before finding a teammate.
Many questioned the tall Belgian's ability when he first set foot in the Premier League but has since settled and learnt to play to his strengths. No doubt Fellaini has ability, but Chelsea's style of play is perhaps more fluent than what Everton play at Goodison Park, and Fellaini may just slow things down. His lack of responsibility in his own box has reared it's head with many feeling he's better in a more advanced role.
Overall, Fellaini isn't as complete a midfielder as Lampard, and doesn't seem to suit the style of play big spending Roman Abramovich demands. If Chelsea do want him, Everton are reported to want upwards of 20m.
Luka Modric - Real Madrid and Croatia
It's no secret that Luka Modric appeared on Chelsea's radar before his big-money move to Real Madrid - the Blues were said to have bid upwards of £40 million almost a year ago.
The tricky Croatian seemed the perfect fit for Jose Mourinho's side, allowing him to show his talents at one of the biggest clubs in the world. But he has struggled to fit in at the Bernabeu with a series of mediocre performances.
This recent run of poor form has lead to speculation that a return to England could be on the cards. Whilst Modric has undeniable ability, he is no Frank Lampard in terms of goals scored.
The England international continues to find the net regularly and although Modric isn't goal-shy himself, his recod pales insignificant to Lampard's. Modric scored 17 times in his four-year spell at Spurs, scoring just once for Madrid.
In my opinion, Modric seems like a good fit for the Champions League winners and the Stamford Bridge faithful would welcome the Croatian with open arms.
Willian - Shaktar Donetsk and Brazil
The Ukrainian-based midfielder first came into the public eye after a series of impressive performances in the Champions League during the 2011/12 season.
Willian has a range of talents - quick feet with a clever footballing brain - while having a somewhat physical presence for someone of his passing ability and stature.
His ability to hold onto the ball whilst finding an incisive pass makes him an attractive attacking prospect for any team. One problem the Brazilian midfielder may have is adapting to the pace and power of the Premier League, with England's top tier renowned for its combative edge.
It seems unlikely that Chelsea would risk paying a large amount to lure Willian when they possesess so much flair going forward already.
Overall, Chelsea have a real issue on their hands when looking to replace such an influential midfielder.
Lampard's distribution of the ball means he can dominate play before finding the final pass, his goal-getting is second to none and if anything, Chelsea should do whatever it takes to keep Lampard.
That said, if the Blues stance doesn't change and Lampard leaves Stamford Bridge in the summer, Luka Modric would be a fantastic replacement, and available at the right price, he may be an attractive proposition to the powers that be at Chelsea.
