United sweep past West Ham, Arsenal ousted by Southampton

LONDON ( Reuters) - Anthony Martial and Zlatan Ibrahimovic scored twice each to help Manchester United ease into the League Cup semi-finals with a 4-1 home victory over West Ham United on Wednesday as Arsenal suffered a 2-0 home defeat by Southampton.

Martial netted twice in the second half to take the tie at Old Trafford away from West Ham, who had levelled through Ashley Fletcher following Ibrahimovic's opener after two minutes. The Swede added the fourth deep into stoppage-time.

Southampton clinched their first appearance in the last four of the competition since 1987 with powerful first-half efforts from Jordy Clasie and Ryan Bertrand against a weakened Arsenal, who made 10 changes to their side.

United and Southampton will be joined in the semi-final draw by Liverpool, who beat Leeds United 2-0 on Tuesday, and Hull City.
