Swansea manager Paulo Sousa admitted to being frustrated by his goal-shy side as they failed to make their superiority count in their goalless draw against Doncaster in the Coca-Cola Championship clash at the Keepmoat Stadium.

Strikers Craig Beattie and Gorka Pintado were the main culprits as they both spurned excellent chances during a first half dominated by the Welsh side.

Beattie headed a Mark Gower corner over the bar and fired straight at Neil Sullivan, while Pintado failed to connect with a Thomas Butler cross with the goal at his mercy.

Butler himself then hit the crossbar after getting his head to a Mark Gower corner.

Their failure to find the net means the Swans have now failed to score in five of their 10 fixtures to date in the Championship.

Former Portugal international Sousa said, "There is a big frustration, not just for me but for all the players.

"I am very proud of the work the lads put in. In the first half we got our strategy right and we had a minimum of four clear opportunities to score.

"Games like this, and the recent game at Barnsley, have to be won as games like this can put us in a completely different position in the table."

But the 39-year-old refused to criticise Pintado when asked for his opinion on the Spanish striker's display.

"It is not only about Gorka, the most important thing for me is to see a minimum of three or four players in the box attacking the areas we need to attack," he said.

"I don't just want strikers to score, I want wingers, midfielder and defenders to score too. I am happy with what happened tonight but I am frustrated because we deserved two more points and we didn't get them."

Doncaster boss Sean O'Driscoll heaped praise on the visitors and admitted he was glad to come away with a point.

"They are better than us in a lot of aspects, but I thought we kept going and that was probably a point won rather than two points lost," he said.

"We have conceded goals where someone has made a mistake but the chances they created were down to good football and passing and movement.

"Every time we play Swansea they set the standard. We've had to sell a couple of players and we had a couple of guys out through injury so we have not got that fluidity that they have got. I'd watch them every week if I could."

But O'Driscoll is hopeful that James Coppinger and Jason Shackell will be fit for Saturday's trip to Sheffield United after both missed tonight's game through injury.

"James trained on Monday and his calf reacted this morning while Shackell trained this morning," said O'Driscoll.

It was a difficult one over whether to throw them in or not.

"With Jason we're not quite sure what the injury is but if there is no recurrence and he feels fine he should be fit, as should James."
