Bolton cruised into the fourth round of the FA Cup at Doncaster's new Keepmoat Stadium, with two goals from Iran international Andranik Teymourian and one each for Kevin Davies and Idan Tal.

Wanderers' fringe players gave manager Sam Allardyce plenty to think about as a much-changed line up gave Coca-Cola League One promotion-chasers Doncaster a footballing lesson.

Midfield playmaker Andranik, signed by Allardyce in the summer after appearing in the 2006 World Cup finals, slammed home the fourth goal soon after the restart to put the game well beyond Rovers.

Doncaster made two changes from the side who helped mark the first match at their new £32million home on New Year's Day with a 3-0 league win over Huddersfield.

Gareth Roberts (suspended) and Paul Green were replaced by James Coppinger and Brian Stock respectively.

Bolton made wholesale changes - goalkeeper Ian Walker, Abdoulaye Meite, Stelios Giannokopoulos, Ricardo Gardner, Andranik, Quinton Fortune, Ricardo Vaz Te and Tal all drafted into the starting line-up.

Paul Heffernan had claims for an early penalty waved away when Abdoulaye Faye caught him while chasing a through ball into the penalty area.

But otherwise neither side fired a shot on target in the first seven minutes.

Bolton then stunned their hosts when Stelios took advantage of Stock's slip in midfield and clipped a fine ball through to Davies.

Davies, made captain for the day with Gary Speed on the bench, showed Premiership class as he applied an expert finish - tucking his volley inside home goalkeeper Ben Smith's far post.

Mark McCammon almost headed Doncaster level soon afterwards from a free-kick out wide - but Walker, in for Jussi Jaaskalainen, pulled off a superb one-handed save.

The early goal they had conceded appeared to galvanise Rovers.

Adam Lockwood headed just over from a corner, and there was more purpose to their play.

But Bolton looked dangerous on the break with the interchanging Stelios, Davies and Vaz Te proving a handful.

Smith then kept Rovers in the game with an excellent save of his own to deny Andranik from Vaz Te's ball in.

Moments later, though, Bolton took a two-goal lead - Andranik this time giving Smith no chance with a shot with the outside of his foot from inside the penalty area.

Rovers were now being run ragged by Bolton's slick interpassing.

Heffernan tried to make space for himself on the edge of the area but dragged his low right-foot shot wide.

Tal took advantage of more sloppy defending to score a controversial third.

The Wanderers midfielder latched on to a bobbling ball to arrow in a shot which Smith did well to block, but Tal followed up to thump home the rebound only for the linesman to raise his flag for offside. Referee Dermot Gallagher was not convinced there had been any interference, however - and after consulting his assistant, he decided the goal should stand.

If Doncaster had a mountain to climb as the second half kicked off they were soon looking at Mission Impossible when Andranik grabbed his second and Bolton's fourth.

The Iranian international burst into the penalty area as Bolton broke down the left and thumped home a square pass from Davies.

Doncaster's afternoon was summed up in one particular break up field. James Coppinger's excellent 40-yard pas set Heffernan away - but when he was one-on-one with Faye on the edge of the penalty area the Irishman was comfortably hustled off the ball before he could get in a shot.

Heffernan saw another rare chance inside Wanderers' area thwarted by the same defender and then fired a right-foot shot narrowly over the bar.

Mark Wilson inspired Rovers' best move of the match, as he raced clear down the right and found substitute Jason Price in the area, but his effort on the turn was blocked.

The sight of French striker Nicolas Anelka coming on for Davies in the 74th minute did little to comfort Doncaster's fans, but captain Graeme Lee almost did when his far-post header flew narrowly over the crossbar.

The second half fizzled out as the clock ticked down, and the majority of another sell-out Keepmoat crowd had left their seats several minutes before the final whistle.
