Rooney left off United's 20-man squad ahead of Saint-Etienne tilt

Wayne Rooney will have to wait until the weekend before making his return from injury after being left off Manchester United's squad list ahead of Wednesday's match against Saint-Etienne.

The United captain, Matteo Darmian, and Luke Shaw are absent from manager Jose Mourinho's 20-man squad that will travel to France for the Round of 32 encounter.

Rooney's absence is somewhat surprising considering he managed to participate in training Tuesday after being sidelined by a muscle strain for almost a month.

His exclusion from the match is understandable, however, considering United holds a 3-0 advantage heading into the encounter after securing a decisive win at Old Trafford during the first leg.

Instead, Rooney - who has not featured since United's FA Cup win over Wigan on Jan. 29 - could return Sunday during the EFL Cup final against Southampton at Wembley Stadium.

Meanwhile, a suspension will force Ander Herrera to miss the Europa League match as well.

De Gea, O'Hara, Romero; Bailly, Blind, Fosu-Mensah, Rojo, Smalling, Valencia, Young; Carrick, Fellaini, Mata, Mkhitaryan, Pogba, Lingard, Schweinsteiger; Ibrahimovic, Martial, Rashford
