For much of the last month, Chelsea have struggled to replicate the form which first got them to the top of the Premier League table but with an eight-point lead still intact, boss Antonio Conte will now be looking for efficiency over goals as they look to end the hopes of their title rivals.
Their last top-flight fixture away at Burnley was an example of how teams are slowly adapting to a 3-4-3 formation that had previously seemed impenetrable, but the Blues showed in that match that they can still pick up points when they are not necessarily at their best.
Conte will be slightly concerned about their failure to create many clear-cut opportunities at Turf Moor – the same occurred against Wolverhampton Wanderers in the FA Cup – but they remain a strong unit at the back and it is difficult to see how any team can enjoy frequent success during a 90-minute period.
Since the end of October, Chelsea have conceded two goals in a match on just three occasions, meaning that when Diego Costa and Eden Hazard are firing on all cylinders, it leaves little chance for the opposition.
That said, Costa has netted just twice in his last seven outings, while Hazard’s only contribution in his last five appearances is his wonder-strike against Arsenal.
Pedro is arguably Chelsea’s key man right now with six goals from eight games, but whoever takes responsibility in the final third, Swansea are up against it to halt Chelsea’s run of 11 successive wins at Stamford Bridge.
