Maresca says Chelsea must 'understand why' they keep squandering leads

Saturday's 2-1 defeat by Aston Villa was the third time this season the Blues have lost at Stamford Bridge after being in front. Ollie Watkins struck twice in the final 30 minutes as Maresca's men were left regretting several missed chances after Joao Pedro gave them a first half-lead. In September, Brighton staged a similar comeback with a trio of late goals in a 3-1 win after Trevoh Chalobah had been sent off. The following month Sunderland scored deep in stoppage time as they came from behind in a 2-1 success.
