ANTONIO Valencia is set to make his United debut against Boca Juniors in Munich on Wednesday. The £18m summer signing from Wigan missed the Reds' tour of Asia while recovering from an injury picked up while playing for Ecuador. But on Monday he joined up with the squad in Bavaria along with Nemanja Vidic and Craig Cathcart who also missed out on the trip to the Far East. The match against Boca kicks-off at 5.30pm with the Reds in action again on Thursday against either Bayern Munich or AC Milan. Meanwhile, Serbian winger Zoran Tosic welcomed his run out in United's final game in China where he scored in the 8-2 victory over Hangzhou Greentown. "It was important to score a lot of goals," said the former Partizan Belgrade man. "I've enjoyed my first tour and I hope there will be more with United." Who will be United's first choice wingers this season? Have your say.
