Frank Lampard endured a frustrating opening game in charge of Chelsea in a competitive fixture as his side were beaten 4-0 by a clinical Manchester United on Sunday afternoon. 

Despite controlling large periods of the first-half, United went into the break 1-0 up thanks to Marcus Rashford’s penalty, after the forward was fouled by Kurt Zouma inside the opening 20 minutes.

The Blues saw two efforts strike the woodwork prior to half-time, with Tammy Abraham’s early effort inside five minutes nearly giving Lampard the perfect start at Old Trafford.

Emerson also saw his close-range shot bounce away off the crossbar in what was an encouraging first 45 minutes under Lampard.

Defensive frailties came to the fore in the second-half, however, with Anthony Martial, Rashford and Daniel James all finishing quick counter-attacks as Chelsea pushed for a way back into the game.

Here are four things we learnt from the Blues’ opening game of the season.
