Previously unbeaten, the visitors were undone by Minhyeok Yang, who capped a magnificent week by bagging a 23rd-minute winner for John Mousinho’s men.
Pompey had to dig deep defensively for long spells, yet did so magnificently, ensuring Josef Bursik barely had a save to make as they kept Middlesbrough at bay superbly
13. Mark Kosznovszky - 6
(Replaced John Swift on 58 minutes) Put plenty in but with Pompey defending had little chance to attack. Photo: Simon Roe
14. Terry Devlin - 7
(Replaced Jordan Williams on 64 mins) Chosen ahead of Swanson to replace Williams at right-back and didn't let the head coach down. Full of energy, fight and drive. Photo: Simon Roe
15. Adrian Segecic - 6
(Replaced Conor Chaplin on 64 mins) Rather quiet, but has that explosive energy and fight which Pompey needed as they defended their lead. Photo: Dan Istitene
