Elliott Dickman has challenged promising Sunderland winger Benji Kimpioka to build on his hat-trick for the Under-23s.
The 17-year-old Swedish winger bagged the matchball in the 5-0 win over mid-table Wearside League club Hartlepool in the Durham Challenge Cup tie at Hetton.
Sunderland fielded a young side for the game, played behind closed doors at Eppleton CW.
Kimpioka was introduced at half-time, replacing Jack Diamond who had opened the scoring, and the teenager wasted no time adding a third after Dominic Moan’s penalty.
Kimpioka fired under Coils just after the hour mark, his second goal extended the lead to 4-0 with 12 minutes left, converting Josh Robson’s right-wing cross and the Swede soon completed his hat-trick, driving an effort through a crowded goalmouth to make it five.
Under-23 coach Dickman said: "The under-18s staff, Mark Atkinson and Michael Proctor, spoke a lot about Benji and certain aspects of his game.
"To be fair to him he did that. He made good decisions in possession, he had some shots and scored three good goals.
"He has been a little bit guilty of not doing that but he has taken on board the information he has been given by the staff and he has got to keep building on that now."
The Sweden Under-17 international, comfortable on either wing or in a No.10 role, signed for Sunderland in the summer of 2016.
"We played some good football and we dominated the ball which was good," added Dickman.
"Some of our possession play was good, it was nice to score five but we could’ve had a few more.
"I am pleased to go through and I thought the lads approached the game well."
