WATCH: Tammy Abraham and Mason Mount claim all three points for Chelsea against Aston Villa
Chelsea secured victory in the Premier League against Aston Villa following back-to-back defeats against Manchester City and West Ham.
On an evening where Chelsea were desperate to get the three points, Lampard made changes, plenty of them too - five to be precise.
His changes were rewarded as he saw his side claim a narrow victory against Dean Smith's Aston Villa side who were despite the tight scoreline, dominated by Chelsea for the majority of the evening.
GOAL! CHELSEA 1-0 ASTON VILLA [ABRAHAM 24']
Tammy Abraham was on loan with the Villans last term, but played against his former side on Wednesday. He showed them what they had last season, and he grabbed the opening goal of the game.
Reece James' delivery into the box midway through the first-half found the 22-year-old, and Abraham headed past Tom Heaton in front of the Shed End, to put Chelsea ahead.
GOAL! CHELSEA 1-1 ASTON VILLA [TREZEGUET 41']
Chelsea's possession and dominance with the ball was all undone just before the half-time break.
Sloppy defending by the hosts allows Ahmed El Mohamady cross a low delivery into the Chelsea box, and Trezeguet bundled it home to level it up for Dean Smith's side in West London.
