Ashley Cole has always been one of the first name on Chelsea's teamsheet during his seven-year spell at the west London outfit.
The former Arsenal defender has been a mainstay on the left-hand side of Chelsea's defence under nine different managers since moving across London in August 2006.
Jose Mourinho enticed Cole to Stamford Bridge and even went as far as tapping him up - in hope that the England international would be able to replicate his outstanding Arsenal form at Chelsea.
Cole said back in July - when Mourinho returned to Chelsea - that he owed Mourinho because: "I didn't play as well as I could back then, and as well as I have for Chelsea since, when he bought me."
It seems slightly peculiar that Cole's two spells of bad form have come while playing under Mourinho.
The Portuguese tactician last week moved to assure Cole that he was being left on the sidelines due to a small knock rather than poor form.
However Cole has since played 53 minutes for the England national team against Germany and is surely fit enough to start, if he is fit enough to be selected on Chelsea substitutes' bench.
Cole has not played for his club since he was dropped after his poor performance against Newcastle United, when his side lost 2-0 at St James' Park.
Mourinho has instead opted to play right-sided full-back Cesar Azpilicueta in Cole's position for his side's matches against Schalke, West Brom and West Ham.
The 33-year-old is already in danger of losing his England slot to Leighton Baines ahead of the World Cup and if he remains on the bench then Roy Hodgson would have no choice but to pick the Everton man over Cole.
Cole will not want to leave Chelsea in January - but he may not have a choice if he has not wormed his way back into Mourinho's first-team plans by the end of December.
The Chelsea star has to be playing regularly in order to start England's opening group match next summer, in what will surely be Cole's last chance of playing at a World Cup.
A club like Liverpool would give him the perfect platform to be able to convince Hodgson that he deserves a starting berth over the equally as good Baines.
Cole would be an excellent signing for Liverpool as he is can play at left-back or left wing-back, which is important as Brendan Rodgers' sometimes opts to play with a 3-5-2 formation, and is a significantly better footballer than both Jose Enrique and Aly Cissokho.
There's no denying that Cole is happy at Stamford Bridge when he is playing week-in, week-out. However Cole must be hurting at the moment and he will be desperate to play in his fourth World Cup, which could prompt the defender into looking for a new club in January.
