Manchester United midfielder Juan Mata has promised supporters that the team's "bad streak will pass".
The Red Devils exited the Champions League last week because of a 3-2 defeat to Wolfsburg.
Following that result, Louis van Gaal's side were beaten 2-1 by Bournemouth in the Premier League on Saturday evening.
In his weekly blog, Mata wrote: "For me, writing is complicated when all I really want now is to have another game to play as soon as possible. But everything passes and this bad streak will pass.
"In these moments is when we have to stick together more than ever, I do believe it, because, luckily, football gives you another game every few days. We are aware that we have to get better and that's why, despite feeling so bad after a painful defeat, we have to stand up and keep working to prepare the next game.
"With the right attitude and each of us giving the maximum we will get out of this situation. This is a long season and there's still a long way to go. We will never give up, that's for sure. December is a difficult month and it's time to start winning again and get our confidence back."
United are currently fourth in the league table, just four points off current leaders Arsenal.
