MANCHESTER, England, Oct 30 (Reuters) - Casemiro and Bruno Fernandes scored two goals apiece as Manchester United ( MANU ) eased into the League Cup quarter-finals with a breathless 5-2 victory over Leicester City on Wednesday, their first game since the sacking of manager Erik ten Hag.

United's interim manager Ruud van Nistelrooy had promised excitement and goals in his first match in charge, and his players did not disappoint.

Casemiro opened the scoring in the 15th minute when he lashed a strike from 20 yards into the top corner and Alejandro Garnacho doubled the lead when he rifled a shot into the roof of the net from Diogo Dalot's cross.

Leicester's Bilal El Khannouss pulled a goal back, but Fernandes restored United's two-goal lead when his free kick struck a player in the wall and went into the net.

Casemiro completed his brace in the 39th minute when he headed the ball against the post before smashing in the rebound.

Conor Coady pulled one back for Leicester in first-half stoppage time, but the visitors' hopes were short-lived as Fernandes latched on to a back pass, dribbled around the keeper and scored his second in the 59th minute.
