Rio Ferdinand has slammed the referee's decision to award Chelsea a crucial penalty in their 2-0 win over Borussia Dortmund.
The Blues were given the spot-kick in the 53rd minute of their Champions League last-16 second-leg clash, with the aggregate score tied at 1-1 at the time.
Kai Havertz stepped up to score the penalty - at the second time of asking after initially missing - but, afterwards, there were questions over the spot-kick decision.
The referee decided to award Graham Potter's side the crucial spot-kick after Ben Chilwell's cross struck the arm of Marius Wolf from close range.
