Ander Herrera has urged his Manchester United team-mates to maintain their focus as they enter a run of games that could define their season.
Ole Gunnar Solskjaer's side travel to Fulham on Saturday - live on Sky Sports - before hosting PSG in the first leg of their last-16 Champions League tie next Tuesday.
United then go to Chelsea in the FA Cup before a Premier League clash with table-toppers Liverpool, but Herrera says United cannot look beyond Fulham.
He said: "It will be a big mistake if we think further than Fulham. That's a massive game for us because Chelsea are playing (Manchester) City.
"Let's go game by game, because if you lose one game you regret. Now for Fulham, then we will think about PSG.
"The best way to prepare for the PSG game is to try and win away at Fulham and that's the way I think."
United will go into their pivotal period of games in excellent form, having gone unbeaten in the 10 matches since Ole Gunnar Solskjaer became caretaker manager.
However, Herrera warns it will be impossible for the side to avoid defeat between now and May, saying: "That is impossible, the Premier League is so tough, City is a fantastic team and they lost away at Newcastle the other day.
"In the Premier League it's impossible to go unbeaten from when the manager came in, to have 25 or 30 games unbeaten."
Although he believes he will have to endure defeat again before the end of the campaign, Herrera is enjoying life under the former United striker - but is avoiding comparisons with his predecessor Jose Mourinho.
"We are very happy with him at the moment, but I'm not going to do comparisons," said Herrera. "I am only going to speak about what is happening now. I'm not comparing.
"We are very happy with him, everyone feels free. We're playing with a lot of freedom, this is one of the things he is talking about every day."
