It was the Doncaster chairman who revealed to the Yorkshire Post last January the vision that had come to him one night while asleep.

The dream featured his beloved Rovers walking out at Wembley five months later to contest the League One play-off final against Yorkshire rivals, Leeds United. Not only that, but Ryan's reverie saw the Elland Road club beaten 2-1 as their south Yorkshire rivals ended a 50-year exile from the second tier.

Ryan's scoreline prediction may have been slightly out, but otherwise his fantasy proved prophetic as one of the truly great revivals in modern day football continued courtesy of James Hayter's second-half winner at Wembley.

Ten years on from being as low as a football club could possibly be without going under, Doncaster were suddenly back in the big time – a fact that was underlined during the summer when the fixtures computer handed Sean O'Driscoll's men an opening day trip to newly-relegated Derby County.

Pride Park seemed an entirely fitting venue for a club who had rediscovered its self-esteem.

And so it proved as, 11 weeks on from that Wembley triumph, Doncaster chief Ryan was back in dreamland as his Championship newboys claimed a fully deserved victory.

Lewis Guy may have netted the only goal just before the hour mark to silence a capacity Pride Park crowd, but it was the manner of the visitors' performance that most pleased Ryan and the ecstatic travelling army of 3,000 fans.

The Rams, featuring seven debutants, were out-played to such an extent that if Andy D'Urso had played 60 minutes of stoppage time at the end of the game as opposed to six, it is unlikely that an equaliser would have materialised.

The Doncaster manager was rightly proud of his players after the final whistle, though quick to stress that no-one should get carried away by winning one game.

O'Driscoll said: "It can only be called a good start after 10 games, not 90 minutes. We have to play well in 46 games and then what will be, will be.

"But the players are up for a challenge. They think they are Championship players, we just have to give them their heads and let them prove it."

On the evidence of the opening day, the Rovers players will not look out of place in the second tier.

Against a club who were two divisions higher last season, they played some delightful football that the home side simply could not match.

Doncaster frustrated the Rams by keeping possession and stroking the ball around with confidence, one second-half move featuring 19 consecutive passes being so impressive that it drew cries of 'Ole!' from the visiting fans.

Perhaps the most impressive feature of their play, though, was the manner in which the Rovers players stayed cool when under pressure.

This was never better illustrated than in the 72nd minute when four opponents were closing in on defensive duo Gareth Roberts and Sam Hird near the left-hand touchline.

The situation smacked of danger, but both stayed calm and simply played their way out of trouble with some lovely inter-play that drew a deserved round of applause from the crowd.

As well as the visitors played, however, they did benefit from two glaring misses by the Rams in the opening half hour.

First, a free-kick from the excellent Kris Commons on 15 minutes picked out Martin Albrechtsen unmarked at the far post only for the defender to inexplicably head wide from close range. Then, 11 minutes later, former Leeds and Sheffield United striker Rob Hulse should have done better than strike a post after quick thinking from both Commons and Tyrone Mears down the right flank.

Paul Jewell suggested after the game that had either of those two chances been taken, the game would have been very different.

It was difficult to argue with the former Bradford manager as Rovers visibly grew in confidence as the first half wore on with the scores level, Brian Stock creating an excellent chance for Guy just after the half hour only for the Rovers striker to shoot weakly into the arms of Roy Carroll.

It was a major let-off for the home side, but a temporary one with the visitors going ahead on 59 minutes after a rolled pass from James O'Connor on the right flank was cleverly dummied by James Hayter.

Had the Rovers man touched the ball then Guy would have been offside when controlling the ball, but instead he was afforded sufficient space to roll a shot past Carroll and into the bottom corner of the net.

There was no way back for Derby and come the final whistle, it was not just Ryan who was dreaming about what may lay ahead this season but also 3,000 ecstatic Doncaster fans.
