Frank Lampard is a bonafide Chelsea legend. He's been arguably their most consistent performer ever since he joined the club from West Ham in 2001, while last season he become the Blues' all-time top scorer.
However, the England international turns 36 in June, and by that point he may have been released by Chelsea.
The star midfielder's contract expires at the end of the season, so who should Chelsea be looking at to fill his shoes?
Xabi Alonso | Real Madrid
Spain international Xabi Alonso is five years younger than Lampard, but he possesses just as much quality and experience.
The Real Madrid midfielder could leave the Bernabeu at the end of the season, so Chelsea could bring in the classy former Liverpool midfielder without paying a single penny.
Paul Pogba | Juventus
If recent rumours are to be believed, Chelsea have already identified the hugely talented Paul Pogba as the perfect long-term replacement for Lampard.
The 20-year-old, who was previously at Manchester United, is already a key player for both Juventus and France.
The Blues would need to pay a small fortune to land the midfielder, but it would be well worth it.
Nathaniel Chalobah | Chelsea
But instead of paying a hefty fee on a 20-year-old, perhaps Chelsea should look in-house for the ideal Lampard replacement?
Blues' legend Gianfranco Zola believes 18-year-old Nathaniel Chalobah has the talent to one day succeed the England international after coaching him at Watford, so watch this space.
Marco van Ginkel | Chelsea
And if Chalobah doesn't work out, then maybe the young Netherlands international Marco van Ginkel will.
The 20-year-old is currently on the sidelines after suffering an anterior cruciate ligament injury, but he showcased his immense promise during a three-year spell with Vitesse.
Chelsea paid £8m for him in the summer - a fee which could eventually look a bargain.
Miralem Pjanic | AS Roma
Miralem Pjanic has long been on the radar of Premier League clubs, including Chelsea, but there were doubts that he would ultimately fail to fulfil his potential - until this season, that is.
The Bosnia & Herzegovina international has been superb with Serie A leaders AS Roma this season - and, at the age of 23, would be ready to slot straight into Chelsea's midfield and fill the void left by Super Frank.
