Preview: In the Great Britain men's football team's first appearance at the Olympics for over half a century, they are now just one game away from competing for the glory of taking home a medal. After difficult beginnings, the relative formality of Britain's progress to this stage of the competition has been an impressive surprise.

Following the controversies of forming a squad between some disgruntled home nations, GB began with a friendly loss to Brazil followed by a struggling draw with Senegal to begin their Olympic campaign.

But after fighting off a comeback from the United Arab Emirates, Britain secured progress to the knockout stage with a composed 1-0 victory over one of the pre-tournament favorites, Uruguay.

Having had little time to work with his squad, coach Stuart Pearce looks to have found a successful system with one central striker and Craig Bellamy wreaking havoc down either flank.

Pearce, though, is faced with several selection dilemmas for the clash with South Korea. Captain Ryan Giggs was left out against Uruguay and may well come back into the side at the expense of Scott Sinclair, with Aaron Ramsey moving back to the left. James Tomkins could also be a candidate to return in central defense.

While Britain will be favorites against South Korea, nothing can be taken for granted against a solid side ready to take advantage of any frailties in the home team.

South Korea's progress to the quarterfinals has been efficient rather than spectacular. Two goalless draws with Gabon and Mexico sandwiched their vital victory over Switzerland. The scorer of the opening goal in that win was Arsenal's Park Chu-young, who is likely to spearhead the attack against Great Britain. Another player GB will need to watch for is Celtic's Ki Sung-Yueng. The talented midfielder has been linked to the likes of Liverpool and Queens Park Rangers this summer.

Prediction: Conceding just one goal in three matches, Great Britain certainly shouldn't expect an easy ride against South Korea, despite having in theory secured an easier path in the competition by winning their group. Expect it to be tight and tense right until the very last. But ultimately Great Britain should get the breakthrough, especially with Welshman Craig Bellamy likely to be inspired once more playing in front of his home nation's fans.
