Scotland prop Allan Jacobsen says as long as they cut out their usual silly errors they have a great chance of upsetting England at Murrayfield on Saturday.
Jacobsen says errors have undermined Scotland's Six Nations campaign so far this year, where they currently languish at the foot of the table with three defeats from three.
29-year-old Jacobsen believes there was cause for optimism in Scotland's performance in Ireland in their last outing, and if they improve again they can spring a shock on England.
"The scoreline doesn't lie but I felt that we played lot more rugby against Ireland," said the Edinburgh loosehead.
"We went out and had a real go at them and the silly errors let us down."
"We've made a lot of stupid mistakes and that has been the main cause of our downfall, so if we can cut that out I'm sure you'll see the sort of performance which can really cause England problems.
"But we need to go into these games with that desire to play good rugby if we are going to win games in the Six Nations."
England are big favourites for the Calcutta Cup match at Murrayfield, with Brian Ashton's men still in with a chance of claiming a tight Six Nations championship.
Frank Hadden will have something to say about that though, and Jacobsen is hoping to maintain his place in the side after starting in all three Six Nations ties this season.
Jacobsen tore a calf muscle in the opening match of the World Cup and was ruled out of the tournament - and he is looking to make up for that disappointment by nailing down the number one jersey.
"After the World Cup I just wanted to get back playing for Edinburgh, try to build my fitness back up and from there try to get involved in the Six Nations, so in that sense my season has gone according to plan," he said.
"Obviously things haven't gone well for us in the Scotland, but I've been lucky enough to start the last three games.
"Hopefully I'll get another chance against England, but I don't want to talk too much about that because I'll end up getting binned.
"If selected this will be the first time I've started a match against England, and I've never played them at Murrayfield before so, personally, I'm really looking forward to it.
"It's going to be a huge challenge, but these are the sort of games that you play rugby for."
