Port Vale manager Micky Adams highlighted the contribution of his young central defenders Jack Grimmer and Joe Davis after they stood firm to frustrate lowly Shrewsbury Town in a 0-0 draw.

The Shrews created the better of the handful of chances throughout a poor game at the Greenhous Meadow but Vale had few problems in registering a point.

"I think probably a point has suited us more than them," said Adams. "We didn't really have the composure that was needed in the final third to cause them many problems."

To that end, Adams was pleased with his side's defensive solidity which was built around strong displays from Davis and Grimmer, who is on loan from Fulham.

"We've had two clean sheets (in the last two games) so you can't knock it," said Adams. "I thought the two young centre halves in particular are learning their trade and are learning every game.

"As a combination, they look decent but we can never take our defending for granted.

"We have to make sure we prepare properly for every game and take all the principles of defending off the training ground into games and I was really pleased with them.

"They looked composed and stood up to the task well. They're getting better."

Shrewsbury's energetic midfielder Ryan Woods twice called Vale goalkeeper Chris Neal into action in the second half.

But a stalemate looked the most likely outcome well before the end as Shrewsbury failed to score for the seventh time in their last eight home outings.

They remain deep in relegation danger but Mike Jackson, Shrewsbury's caretaker manager, felt there were some positives to emerge.

Jackson, in charge for the last four games following the resignation of Graham Turner, said: "We've had a clean sheet, we've picked up another point at home and there's been encouraging signs from where we were when I walked through the door, or into this seat.

"The club's in a better place as regards the players and what we're doing."

Jackson felt his side just edged the contest overall having fashioned the clearer openings in a tight match.

"I wouldn't say we totally dominated the game but I thought there was a bit of grit about us, a bit of spirit, and that was pleasing, so was the clean sheet," he added.

Jackson opted for a different approach by selecting three central defenders and described one of them, Jermaine Grandison, as "outstanding" in managing to limit Vale to very few chances.

He said: "I think it's a decent formation if you play it well, but we just needed that little bit more in the final third."
