DONCASTER ROVERS 1 BRISTOL CITY 0: If nothing else, this frustrating defeat in the Yorkshire chill highlighted City's need for reinforcements when the January transfer window swings open for business next month.

Gary Johnson's team may be reasonably well-placed – ninth and just two points outside of the Coca-Cola Championship play-off positions with the campaign approaching its midpoint – but based on the available evidence to date, they lack the consistency required to establish themselves in the top six.

Stylish in victory at Leicester just a few days earlier, City had good reason to feel confident of becoming only the second team to win at the Keepmoat Stadium this season.

But just when it seemed as though a corner had been turned, they fell short of expectations in a manner which suggests chairman Steve Lansdown may be persuaded to splash the cash in the January sales.

Although the visitors enjoyed more than their fair share of possession, they had precious little to show for it as their more creative influences were found wanting in the face of organised defence.

It should perhaps come as no surprise that City's least productive spell of the season has coincided with a loss of goal-scoring form on the part of leading marksman Nicky Maynard, who has failed to hit the target in any of the last six outings. Once again, he was effectively marked out of the game and his team-mates struggled to muster a cutting edge in the final third.

Manager Johnson publicly stated his intention to recruit a left winger during the transfer window to replace the departed Michael McIndoe and it is becoming increasingly apparent that his team is in need of a forward who can help take the pressure off Maynard on a regular basis.

Doncaster boasts one such player and, sure enough, Billy Sharp was the difference between the protagonists on a day when the two sides cancelled one another out.

Afforded the best goal-scoring opportunity of the game, the former Sheffield United hit-man required no second invitation, demonstrating a poacher's instinct to deliver the decisive blow after 12 minutes.

City failed to make the most of an attacking free-kick, Cole Skuse inadvertently headed a long clearance into the path of Doncaster's most dangerous striker and Sharp did the rest, motoring clear of the covering defence and angling his low shot between Robins keeper Dean Gerken and the far post. Second best for much of the first half, City were briefly energised by the introduction after the break of Alvaro Saborio.

Sure enough, the Costa Rica international tested Neil Sullivan for the first time with a rasping drive, sent another effort fizzing inches wide and then directed a downward header straight at the keeper as City created more chances in a hectic 10-minute spell than in the rest of the game. Saborio's presence initially upset Doncaster and the visitors thought they had equalised on 52 minutes, Danny Haynes meeting a Gavin Williams cross with a sweetly-struck volley which whistled into the roof of the net.

But the former Ipswich man's celebrations were cut short by a linesman's raised flag, after which Rovers held out with few scares.

Television replays showed Haynes had in fact been in an on-side position when the ball was played and the young forward was left to reflect on what might have been.

"I thought the goal should have been allowed to stand," insisted Haynes, whose pace and willingness to commit defenders provided one of the few bright spots on an otherwise disappointing afternoon for the Robins.

"I was sure I was not offside and I caught it just right. Having the goal taken away like that was frustrating and I couldn't quite believe it when I turned and saw the flag go up. It just about summed up our day."

City could have few complaints. Doncaster passed the ball and retained possession better for much of the contest and created the best of what few clear-cut chances were on show.

Certainly, Sharp should have put the outcome beyond reasonable doubt midway through the second half when seizing upon a long clearance from James Chambers, and out-stripping the defence.

Fortunately for City, his radar went awry and his angled shot flashed across the face of goal and beyond the far post.

Unfortunately for the visitors, they were unable to summon the incisive qualities required to restore parity in the 20 minutes or so that remained.
