Manchester United manager Louis van Gaal has not given up hope on his team challenging for the Premier League title this season.
The Red Devils are currently in fifth place, 10 points behind leaders Leicester City.
On Sunday, they take on Chelsea at Stamford Bridge, and despite the Blues' drop down the table, United have only claimed one victory in 13 league visits to the stadium.
Chelsea head into the game on the back of a nine-game unbeaten run, and Van Gaal believes that if his team can nab all three points this weekend, they can restart their title bid.
"Since Guus Hiddink is there they don't lose anymore so it is not so easy so then I think our league [challenge] shall start again - that is very important," Van Gaal told reporters.
"Michael Carrick said that and I had the same feeling. The competition is not finished. Not for Manchester United and not for the other teams. In this competition everything is possible.
"We have the feeling and that is beginning [now] we are winning in a row two times and with sparking football, with goals, with clean sheets, against opponents who were in great form."
In this fixture at Old Trafford on December 28, the two sides played out a goalless draw.
