First Half Hungary 0-1 Scotland March 27 2018
Aberdeen’s McKenna, 21, started again after a debut against Costa Rica, while Celtic’s Hendry, 22, made his debut.
“Scott McKenna was amazing tonight. He had a really strong game,” McLeish told BBC Scotland. “He has had two excellent games and was even better tonight.
“I thought big Jack was very cool and calm and very confident”
Scotland keeper Allan McGregor made several vital saves, one after Mulgrew gave away possession, but the visitors held on in Budapest to earn the first win of McLeish’s second spell in charge.
