KO Mins. HT Mins. A seemingly unimpressed Lampard made three alterations at half-time and it led to an improvement — Tammy Abraham finding the net in the 55th minute, only for celebrations to be cut short by an offside flag.

A Ben Chilwell cross hit the crossbar at the other end, but that was a momentary lapse in Chelsea's second-half domination and they deservedly went ahead just past the hour — half-time substitute Barkley expertly turning in Willian's low cross.

The Blues should have finished Leicester off on the break in the 89th minute, but Barkley's initial pass to Ruben Loftus-Cheek was poor and when the ball was returned to him the former Everton midfielder's shot was saved in unorthodox fashion by Schmeichel.

Few would have taken issue with Lampard's starting XI. After all, the three players taken off at half-time — Mason Mount, Billy Gilmour and Reece James — are all fine prospects.

However, when it was not working out, Lampard was able to turn to the likes of Barkley and Mateo Kovacic on the bench, and both were very bright after coming on.

That he did not tells us much about Lampard the manager enforcing the standards he set as a player. Frank Lampard put in another stellar managerial display as his half-time changes were crucial as Chelsea beat Leicester We lacked urgency and intensity, we seriously lacked it.

Leicester : Schmeichel 6; Justin 6, Evans 6, Soyuncu 5. Chelsea : Caballero 6; James 5. I made the changes I did for impact and to inject some personality.

We haven't played that bad since I've been here. I am sorry if I sound too down, I am very happy we are through.

Lampard loved the FA Cup as a player, his four winners' medals out-numbering his return in any other competition. And so does Barkley, this being his third goal in the Cup this season.

It was also a timely reminder of his worth with the club's recruitment drive in attacking areas showing no sign of letting up. Timo Werner and Hakim Ziyech will join next month and already Chelsea's players are competing for places ahead of next term.

Not that you would know it based on that first-half performance. Indeed, the visitors would have been better served using the mid-half hydration break for an impromptu passing drill.

Instead, Lampard was seen giving particular instruction to Billy Gilmour, the year-old midfielder making just his fifth senior start and of whom so much is expected.

Gilmour, though, had been Leicester's most creative player, so errant was he in possession. The teenager's first wayward pass - inside 20 seconds - should have led to a Harvey Barnes goal but his touch was just as clumsy inside the penalty area.

At least Chelsea's passing was entertaining, albeit from a comedic perspective. Lampard did not see it that way and, after one Antonio Rudiger cross-field attempt landed in the low rows, the manager spun on his heels in disbelief.

Already, you suspect, he was plotting the treble change. That his side made it to half-time at nil-nil owed much to Leicester's own struggle for inspiration in the final third.

Gilmour was again the inadvertent source when his sloppy ball found Youri Tielemans and the Belgian burst forward before drawing a low save from Willy Caballero.
