Port Vale manager Mickey Adams intends to keep his players' feet on the ground after adding an impressive 3-1 victory at Doncaster Rovers to a promising start to the season.

Vale hammered six past Hartlepool United in the Capital One Cup in midweek and continued their fine form to send relegated Doncaster crashing to their first defeat of the campaign.

Adams said: "That was probably as well as we've played away from home since I've been here.

"Doncaster were one of the pre-season favourites for promotion and, let's face it, we were playing against a good side.

"But overall the effort and commitment from my players was spot on and the way we passed the ball and closed them down was very pleasing.

"But we are only two games into the league programme and it's just another victory as far as I'm concerned.

"There's no danger of anyone getting carried away.

"I've got a terrific squad when everyone is fit, but if we get one or two injuries we will be tested."

Doncaster began the game brightly, but fell away badly when Vale took charge to rattle home three goals before the interval.

Ben Williamson followed up his midweek hat-trick in opportunist style when he headed home after Jed Steer had done well to tip away a close-range effort from Michael O'Connor in the 27th minute.

Tom Pope scored for the third game in a row to make it 2-0 with a splendid angled drive that went in off the far post in the 39th minute and skipper Carl Dickinson lashed home the third a couple of minutes later following another set-piece.

Doncaster pulled one back through substitute Kyle Bennett with a looping 25-yarder that caught Sam Johnson off his goal-line 15 minutes from time but never looked like hauling back the deficit.

The home side's miserable afternoon was complete when they had midfielder Harry Forrester harshly sent off in the 79th minute when he appeared to kick Johnson in the face as he tried to shoot for goal after rounding the keeper.

Adams added: "To be fair I thought it was a foul on their goalkeeper for the third goal, but Carl Dickinson stuck it away and that's all he can do.

"I didn't think it was a sending off either. I've seen the video and it didn't look more than a reckless challenge."

Disappointed Doncaster boss Paul Dickov said: "We fielded the same side that started the game in last week's 3-0 win at Yeovil, but didn't get the same response.

"But we didn't get carried away with last week's win and I'm not going to go over the top after losing this.

"The first half was probably as poor as we've been since I've been here, but you have to give Port Vale credit for the way they played.

"The most disappointing aspect for me was that we conceded from two corners and a throw-in and we're going to have to be better than that if we want to do well this season .

"Having said that it was a definite foul on the keeper for their third goal and it was never a sending off - if anything it was a borderline penalty decision because Harry (Forrester) was pushed when he tried to make contact with the ball."
