Man United will attempt to bounce back from three straight defeats when they travel to Northampton Town in the third round of the League Cup on Wednesday night.
Kick off is at 7.45pm (UK time).
The manager, Jose Mourinho must get rid of some of his big name players and he must also change his tactics.
He added: "We will go game after game and try to give the best we have".
The England global has played as a winger or forward since breaking into the first team at Old Trafford last season, but he regularly featured in a deeper role with United's academy. It remains to be seen.
The Portuguese, who known to create outside enemies in hopes of creating a bunker mentality within his teams, was harshly critical of referee Michael Oliver after his side's loss at Vicarage Road. On the injury front, Anthony Martial will be assessed after being forced off in the first half at Watford, while Phil Jones is out for up to a month with a knee injury.
Ex-Patriots' center Bryan Stork visiting Jets
Stork, a fourth-round pick by the Patriots in 2014, has suffered multiple concussions in his first two seasons in New England . The reason for the failed physical was never reported, and Stork, 25, was released by the Patriots the following day.
"All credit to City, who look phenomenal, but I thought Jose would have set up his team to play higher up the pitch".
Hence, he pushed Rooney back into midfield for the Watford clash - something he vowed to never do, in his first few press conferences as Man United's manager.
Zuniga, who kept his match shirt as a memento of the "best goal of his career", insisted no one at the club was getting carried away. He converted the match-winning penalty at West Brom's expense and said afterwards: "When it left my boot I knew it was in and I started running before it hit the net - it was insane". But the fightback to earn a 4-2 win against Slaven Bilic's side clearly flooded the camp with confidence for the visit of United and Watford deservedly secured a second successive League victory.
Rooney has been a key part of United's attack since scoring a brilliant hat-trick against Fenerbahce on his debut for the Old Trafford club 12 years ago after arriving from Everton. United had been talking to us for two years about Pogba.
The match will take place at the Sixfields Stadium.
