Alan McLoughlin believes Jack Whatmough is revelling in his first-team education.
The teenage defender marked his third successive appearance with a clean sheet as Andy Awford’s side defeated Morecambe 3-0.
It was an assured display from the Gosport youngster up against wily veteran Kevin Ellison.
The 35-year-old Morecambe player has seven goals in 17 league games this season and cuts an intimidating figure on the battlefield.
Whatmough had the odd skirmish with Ellison, yet came out on top as Pompey moved up into 10th in League Two.
And for McLoughlin it was another important lesson in the defender’s on-going education.
Pompey’s first-team coach said: ‘I’m pleased for Jack that after his injury he’s got through 90 minutes. That’s great for him.
‘Jack was dealing with 20 years of experience on Saturday in the form of Kevin Ellison.
‘To play against someone like that will definitely help him.
‘Ellison doesn’t stay in one place but drifts around everywhere.
‘It’s a learning curve for Jack, he will benefit from the more games he plays against people like that.’
Whatmough has made 12 appearances so far this season, having been in and out of the side.
Recently he was sidelined for seven matches having injured a hamstring in the goalless draw at York at the start of October.
He returned in a midfield role at Plymouth, before he was restored to the centre of defence against Aldershot.
Morecambe, though, was his first 90 minutes since his injury.
