London, December 3:

Burnley followed their victory over Chelsea by beating Arsenal 2-0 to reach the League Cup semi-finals on Tuesday for the first time in 25 years.

Derby beat Stoke 1-0 to eliminate another English Premier League team, but Burnley’s convincing win over an Arsenal largely made up of their promising youth players was the bigger shock. The northwest England team, which was last English champion in 1960 but was challenging for promotion to the Premier League, beat the Gunners through two goals by Kevin McDonald — just three days after he scored his first for the club.

McDonald gave Burnley a sixth-minute lead when he tapped in a rebound after Arsenal keeper Lukasz Fabianksi fumbled a Chris Eagles cross. Fabianksi also saved a header from Mike Duff and a bouncing half-volley by Robbie Blake before McDonald added another in 57th.

The midfielder, the youngest player in the Burnley team at 20 years old, bustled past 19-year-old Mark Randall in the area to win possession and put the ball past Fabianski . “Obviously the best goals I’ve scored so far,” said McDonald, who joined from Dundee in Scotland in June.

McDonald went off injured in the 60th, but Arsenal was unable to respond and needed Fabianski to save an on-target header by Martin Paterson. Arsenal’s entire starting lineup has a combined 25 Premier League matches for the club, with 21 of those shared by Nicklas Bendtner and Mikael Silvestre. Kieran Gibbs, Paul Rodgers and Fran Merida have never even made a substitute appearance.

Bendtner put two good chances past the post, the second with just four minutes to go when Arsenal was desperate. Burnley, who beat Chelsea in a penalty shootout in the last round, will be joined in the semi-finals by Derby after Nathan Ellington hit an injury-time penalty kick at Britannia Ground.
