Michael Jamieson has vowed to embrace the weight of expectations on his shoulders this week by breaking the world record at the Commonwealth Games in his home city.

The Olympics silver medallist is happy to admit the current best-ever time of 2:07.43 will be in his sights when he goes for gold in Thursday's 200m final at Tollcross, the pool he grew up swimming in.

It would mean improving his own personal best by 0.42 seconds but Jamieson is now prepared to admit that is his target.

He said: "Initially I was a bit nervous about putting it out there but now I think it's better to be honest about stuff like that. It's only natural to want to improve.

"I want to take responsibility and step up and deliver a personal best. If I do that, that's all I can do.

"I expect certain times and performances from myself this week. That is the result of performances in the past few years and the support I've had. That has to be a positive.

"It's the biggest race of my life, no doubt about it.This is our games and the Scots want to put on a show. That means medals."

Jamieson, 25, begins his quest on Thursday, the first day of the competition.

He is arguably the Team Scotland member under most pressure to win gold given his past feats and his role as as an official ambassador for Glasgow 2014. But he is certain he will rise to the challenge.

Jamieson said: "I'm not a robot so there have been times over the past year or so when I've had a mini meltdown. But I think that's natural and overall I think I've dealt with it well.

"I just keep reminding myself that no-one will ever put as much pressure on me as I do myself."

Jamieson arrived in Glasgow yesterday after a training week in Aberdeen and was thrilled to feel the mounting excitement.

He said: "The city looks amazing. Today I was in the athletes' village and I was greeted by about 40 or 50 volunteers. It was brilliant.

"Everyone is getting involved in the buzz around the city. We have a chance to write our name in the history books for hosting one of the best Commonwealth Games ever."
