Peter Beardsley: “You could see Gateshead were a bit ahead of us in terms of their preparation, so I wasn’t too worried.
“Gateshead were men, while we had five kids who can still play in the Academy for us.
“They gave us a lesson, but when we dust ourselves off, have a look at what we’ve seen and get back on the training ground, it will be good for them.
“We’ve got a young team and we understand.
“We’ve obviously got bigger things to come about a month down the line.
“Our club knows it’s not about winning at this level, certainly not in pre-season, and because of that, we’re not too disappointed.”
