Ross Barkley came off the bench to send Chelsea to Wembley as manager Frank Lampard’s half-time changes transformed this FA Cup quarter-final at Leicester City.
The Foxes held sway in the first 45 minutes at the King Power Stadium, although it took a flying save from Leicester keeper Kasper Schmeichel to keep out Christian Pulisic’s powerful drive.
Lampard’s discontent could be heard echoing around the virtually deserted arena – and he acted by introducing Barkley, Mateo Kovacic and Cesar Azpilicueta at the interval for Reece James, the subdued Billy Gilmour and Mason Mount.
It had the desired effect as Chelsea improved markedly. Barkley, who was on target in the 2-0 win against Liverpool in the last round, scoring the winner after 63 minutes when he reacted to get in just ahead of Jonny Evans and sweep Willian’s clever cross past Schmeichel.
Leicester, missing the injured James Maddison, were out of sorts after the break although they applied late pressure and defender Caglar Soyuncu was frustrated late on when his header struck Azpilicueta and flew over.
