Foxes too sharp for Blades at Bramall Lane
Islam Slimani, Demarai Gray and Ahmed Musa reminded Leicester boss Craig Shakespeare of their capabilities by scoring the goals in a 4-1 EFL Cup victory at Sheffield United.
None of the trio has started for the 2016 Premier League champions this season, but Gray's trickery, incision and cool second-half finish demonstrated why Bournemouth have been linked with him.
Slimani - last year a £28million capture from Sporting Lisbon - was maybe fortunate to be in a position to grab a double after somehow managing to avoid dismissal on the stroke of half-time.
He took his goals well once the Sky Bet Championship Blades began to lose heart - they had threatened early on at Bramall Lane through David Brooks.
