Manchester United midfielder Ander Herrera has warned his side that they cannot afford to look further ahead than their next game in the Premier League.
Jose Mourinho's side have won back-to-back league games for the first time since August and will be favourites to extend that streak over the festive period, with matches against West Bromwich Albion, Sunderland and Middlesbrough.
However, Herrera stressed that there are no guaranteed wins in the Premier League and insists that he is fully focused on Saturday's meeting with the Baggies at The Hawthorns.
"[The Christmas period] is key, but in the Premier League, you never know. If we were in Spain I could tell you 'these are the games we are going to win' but in the Premier League you never know. You can beat Tottenham and come here and don't win," he told reporters.
"You never know, you saw Arsenal lost at Everton, Man City lost to Leicester and then Leicester lost at Bournemouth. There are no easy games, the Premier League is the Premier League, the most amazing league in the world and the way I think is 'the next game'.
"The next game is West Brom, we want to win. If you think you are just going to beat West Brom, Middlesbrough or Sunderland, maybe you don't do that so you just think about the next game."
United, who are unbeaten in their last seven league games stretching back to October 23, currently sit six points adrift of the top four.
