Chelsea legend Frank Lampard was disappointed with the performance of the wing-backs for their draw with Champions League opponents Roma.
Lampard says the performance from Davide Zappacosta and Marcos Alonso was a worry because they did not improve after half-time.
“I think it was not getting to grips with what we said at half-time, which was the switch of play," Lampard said on BT Sport when asked what his biggest concern was.
"The wing-backs were not moving out quick enough to close down the Roma full-backs. They let them dominate the game.
"On the plus side for Chelsea, Chelsea do have a knack of scoring in the right times in games.
"They did it twice in the first-half and when you think the game is really getting away from them again, they get another goal. So they can take some credit from that."
