Ron Harris has criticised Chelsea for the poor man-marking at set pieces on Wednesday night.
Jose Mourinho's Blues conceded twice at dead-ball situations in their 2-2 draw with Paris Saint-Germain at Stamford Bridge which saw them exit at the Round of 16 stage of the Champions League.
David Luiz and Thiago Silva powered headers home to give ten-man PSG an away goals win and former club captain Harris was none too impressed.
"I think questions have got to be asked when you have got a goalkeeper and four or five defenders who are 6ft 2ins plus and they score two headers from set-plays," he said.
"They were two poor goals to concede. Even with 10 men, PSG were the better side."
