Ruud Gullit picks holes in Chelsea's 3-4-3 formation
Chelsea missed the chance to move 12 points clear at the top of the Premier League after leaving Burnley yesterday with just a 1-1 draw.
And former Blues midfielder and manager Gullit believes Sean Dyche's men were clever in exploiting Chelsea's weaker left-hand side.
Conte switched to a 3-4-3 formation at the start of September, which sees Marcos Alonso and Victor Moses deployed as wing-backs on the left and right respectively.
Gullit reckons Alonso is often isolated with winger Eden Hazard in a more advanced position, while Pedro is always on hand to help Moses out defensively.
Antonio Conte's side left Burnley with a 1-1 draw
Ruud Gullit says Chelsea are stronger on the right than the left
He told the BBC: "Not many teams have tested Chelsea's three-man defence this season, but Burnley showed there is a way to get at Antonio Conte's side.
"The Clarets were extremely clever in Sunday's 1-1 draw, especially in the way they targeted Chelsea's left flank, which is far less disciplined defensively than their right side.
"Eden Hazard always wanders inside from the left – far more than Pedro does when he starts on the right – which is what happened at Turf Moor.
"That leaves Chelsea's left wing-back Marcus Alonso to advance up the pitch and give them an option wide on that flank.

How did the Chelsea players get on during their clash with Burnley?
"But, with Hazard often on the opposite side of the pitch, Alonso is sometimes left isolated when the Blues lose possession.
"Alonso is also not as strong as their right wing-back Victor Moses when it comes to getting back to help his centre-halves. I look at him and think he is more of a left winger.
"It is a weak spot because it leaves space to exploit if teams can get the ball into that channel behind Alonso, but you usually have to do it quickly.
"Burnley managed it early on by playing long balls up to Andre Gray that forced Gary Cahill and David Luiz to come out wide, out of their comfort zone."
