MICHAEL Tidser believes the fine margins could be vital if Morton are to secure a place in the quarter-finals of the William Hill Scottish Cup later today.

Midfielder Tidser, 28, helped himself to a goal during last weekend’s 2-1 win over Dunfermline Athletic in the league.

And with Championship rivals Dumbarton coming to Cappielow this afternoon on cup business, Tidser believes the key to the game lies with a clinical approach in the final third.

Tidser told Tele Sport: “We’ve been in the same division with them for a few years and we know they are very well drilled and hard to play against.

“It’s like playing most teams in our division, it’s the fine margins that get you over the line and today it’ll be no different.

“We’ll need to be at it and we’ll need to be focused. If we get chances we’ll try to take them and try to get through to the next round, which is the most important thing.”

Ton go into the game on the back of three consecutive victories and Tidser hopes the confidence gained from those wins can stand them in good stead.

He said: “Confidence in football is everything. In life it’s everything. And if you are feeling good about yourself and winning games, it breeds more confidence.

“Albeit, last Saturday we weren’t at our best but we got over the line. 

“Within our camp we know we’re good enough to go and compete but it will be very difficult today.

“But if we give a good account of ourselves then there is no reason why we can’t win the game.”

The Morton midfielder admitted he would love to go further in the competition because it could result in a last-eight clash with one of the big guns.

Last season Morton made it to the last 16 but their hopes ended with a 2-1 defeat to Rangers at Ibrox, a match where Tidser scored the opener.

Tidser said: “The closer you can get to the final, the bigger teams are usually there, so if you can be in about the mix, get into the quarters, then you could maybe get a big scalp at Cappielow — or an away ground like Parkhead or Ibrox, where we had a great day last season, but didn’t get the result we were looking for.

“That was a great experience. We gave a good account of ourselves.”

However, Tidser knows that Ton must first overcome Dumbarton before they start to dream of a possible glamour tie.

He said: “We know how difficult it’s going to be. They will definitely be up for the challenge. Stevie Aitken’s got them playing some good stuff. They do very well for being a part-time team.

“I don’t think he gets enough credit actually. It’s a tough game but one we’re looking forward to.

“If we can get through it would be good to see who we could get in the draw. A good cup run generates a good atmosphere about the place.”
