Lampard gets first home win
Chelsea 7 Grimsby Town 1
Frank Lampard got a first home win as Chelsea boss under his belt as his youthful side thumped League Two Grimsby 7-1 in the League Cup.
Goals from Ross Barkley, Michy Batshuayi's brace, Pedro, Kurt Zouma, Reece James and Callum Hudson-Odoi ensured an ultimately comfortable passage into round four.
But the bigger picture was Lampard handing debuts to four academy graduates as well as a first start for Billy Gilmour.
Gilmour was a stand-out performer in midfield and fellow rookies James and Marc Guehi also impressed, while there was a welcome return for England winger Hudson-Odoi, his first appearance since picking up an Achilles injury in April.
Making 11 changes may have been a risk for Lampard, certainly given the events of 24 hours earlier.
With just four minutes on the clock Barkley collected Pedro's pass 25 yards out and powered past Town midfielder Harry Clifton into the area before firing low inside James McKeown's near post. Three minutes later it was two, Batshuayi spinning in the area before lashing the ball home.
But Grimsby, who lie 66 places below Chelsea, stunned the Blues when veteran Matt Green halved the deficit with a spectacular long-range effort.
Meanwhile, Karl Robinson masterminded another upset as Oxford reached the fourth round for the first time in 22 years following a 4-0 win over West Ham at the Kassam Stadium.
Second-half goals by Elliott Moore, Matty Taylor, Tariqe Fosu and Shandon Baptiste gave the U's a deserved victory
