Everton 3 - 0 Portsmouth
The fullback made his long-awaited return in this Premier League Cup Group F fixture following nine months of patient rehabilitation following the dreadful double leg fracture he sustained on international duty for Ireland in a World Cup qualifier against Wales.
He was joined in the starting XI by Luke Garbutt who is being assessed for his suitability as cover for the injured Leighton Baines at left-back.
Baines remains sidelined with a calf problem and has been deputised recently by Cuco Martina, a right-footed right-back by trade.
Garbutt broke into the Blues' first team under Roberto Martinez, putting in some impressive displays, particularly in the Europa League in 2014-15, but he struggled to impress during subsequent loan spells with Fulham and Wigan Athletic.
Everton dominated the first half hour in a windswept Goodison Park and went close through Antony Evans who flashed a shot wide and the Blues saw another effort deflected behind.
Their best chance in that spell fell to Nathan Broadhead but he snatched at the chance in front of goal and ended up scooping it over.
The forward made amends shortly afterwards, however, when he was picked out in oceans of space in the box by Fraser Hornby and slotted home.
The same duo combined a few minutes later but Boradhead's header off the striker's cross was comfortably saved by the Pompey 'keeper.
Sambou doubled the Blues' lead with a terrific effort from distance early in the second half and both Broadhead and Evans forced good saves from the 'keeper as Everton pressed for more.
They did add to their lead when Sambou claimed his second to make it 3-0.
Everton U23s: Hewelt, Coleman (60 Markelo), Gibson, Feeney, Garbutt, Baningime, Adeniran, Evans, Sambou (Dyson), Hornby, Broadhead (Baxter).
Subs: Hilton, Foulds.
