Micky Adams is convinced Port Vale will need to improve to match League Two's frontrunners this season despite an easy 3-0 opening day win over Barnet.
Crisis-club Vale left their troubles behind them out on the pitch as they surged into an early two-goal lead but later lost impetus, irritating their hard-to-please manager.
"We'd set the tempo, but after about 30 minutes we sat off and let them play a bit,'' said Adams. "For the first 25 minutes of the second half it was painful and we couldn't get going.
"I was delighted with some of our play, but disappointed with some of it too.
"We're going to get bigger tests than that as it will take Barnet time to find their feet under their new manager. We are going to have improve on certain aspects of our game.''
Sam Morsy forced Liam O'Brien to push around a firm early drive. But the Bees keeper was beaten all ends up by Louis Dodds' exquisite finish in the eighth minute. The frontman turned and volleyed into the far corner.
Then Jennison Myrie-Williams - one of Adams' five new signings - slotted in from the penalty spot in the 20th minute after Tom Pope was impeded challenging for a high ball with Barnet striker Jon Nurse.
Pope later capped the opening-day victory when he placed a finish into the bottom corner 15 minutes from time.
New Bees manager Mark Robson was unimpressed with his side's lack of sting up front. The closest the Londoners came to worrying Chris Neal in the Vale goal was when Nurse's deflected effort left the side-netting rippling before the interval.
"It was a tough game for us as Port Vale are a strong side," said Robson. "Physically they were a bit too strong for us. I am disappointed we conceded three and losing two early goals was a big blow."
