Man Utd keeper Johnstone delighted with starring Scunthorpe performance
It was their first clean sheet in 26 Football League matches.
Speaking after the match, the young keeper was understandably delighted with his side's performance.
"It's great to have kept a clean sheet," he said. "It feels good for everyone. We went down to ten men so it was a good result. We even had chances to win it. We all dug in and hopefully it shows that we are a good side and we'll carry it on into next week."
