Tino Anjorin, Ben Stevenson, Kusini Yengi, Abu Kamara and Ryley Towler were the scorers as the Blues defeated the League Two side in the EFL Trophy group stages.

![(Replaced by Koby Mottoh on 81 minutes) Operated behind Yengi, yet lacked the goal threat of his team-mates during that rampant second half. Still, linked up play superbly and keeps the ball so well through his physicality that he can make things happen and it was his pass from which Yengi struck the bar. A popular player for good reason.](https://www.portsmouth.co.uk/webimg/b25lY21zOjMyNWUwYTlkLTVhNTItNGNlOC1iZGEyLTU5MDY0OWVjYmQ2YTpkYzdlMzc3OS0xNGMzLTRmNjctOGUyMC1hZDMyMzhkMzIwMGE=.jpg?crop=3:2&width=800)

![Since dropped to the bench in recent weeks has ramped up his game following a disappointing start to his Pompey career, with Gillingham a lively display back in the starting XI. Involved in Stevenson’s goal which put Blues 2-1 up and later moved from right wing to a central attacking role. Desperately needs first Pompey goal and again came close.](https://www.portsmouth.co.uk/webimg/b25lY21zOjQ5NGI1YmI5LWZhNDctNDRkYS05NzA1LTc1YzFmZjE1Yjc5OTo4OWVmNzBkYi1lYzk0LTQ3NTctYTlhOS0wNGQ0NTQ2NGE1NGY=.jpg?crop=3:2&width=800)

![(Replaced by Conor Shaughnesssy on 63 minutes) Handed his first start since August after recovering from injury and didn’t really spark until the second half.
