Manchester United right-back Rafael da Silva has admitted his teammates are 'hurting' after two successive Premier League defeats.
The Premier League champions lost to Everton and Newcastle United last week, which leaves Manchester United languishing in ninth spot.
Manchester United boss David Moyes is under severe pressure to stop his side's recent slide.
Brazilian right-back Rafael, who has played nine competitive games for Manchester United this season, has insisted his Manchester United teammates are doing everything they can to stop their recent dip in form.
Speaking to Sky Sports, Rafael said: "Of course it hurts. As a United player I want to win every single game.
"We must work more and improve ourselves.
"We have been working in the same way. I think we have been unlucky some games, maybe that is why, since you lose one game you lose a bit of confidence.
"I think we will work the same way and you just have to have a bit of luck some games to try and win and get the confidence back."
Rafael will be hoping his side can get back to winning ways when Manchester United take on Shakhtar Donetsk in the Champions League on Tuesday night.
The Red Devils are currently sitting at the top of Group A - but need to avoid defeat in order to seal top spot.
Moyes may have one eye on his side's weekend clash against Aston Villa, as Manchester United's current league position needs addressing.
