These two could make a huge difference.
The upcoming clash between Manchester United and Liverpool is one of the most eagerly awaited derby clashes between the two in years.
United are enjoying an incredible run of form at the moment.
They have not been beaten since November and this run consists of 15 games undefeated and nine wins on the trot in all competitions.
A win for Mourinho's men against Liverpool will lift them within two points of their fiercest rivals.
Two of the men responsible for this incredible run look set to play a part in the match against Klopp's Liverpool.
Manchester Evening News is reporting that both Zlatan Ibrahimovic and Marcos Rojo are expected to play as they were both spotted arriving at the team's hotel.
The in-form Ibrahimovic missed United's last game against Hull City in the EFL Cup with illness but he is expected to lead the line for the men in red.
Ibrahimovic will look to add to his impressive Premier League tally of 13 goals and he could think of no better time to do it against Liverpool at Old Trafford.
Rojo is also expected to play a part according to reports.
The Argentine is set to re-join Phil Jones in the centre of defence at the expense of Chris Smalling and continue what United fans will hope, is the continuation of a partnership which has had much success this season.
Rojo injured himself in the FA Cup clash with Reading but Mourinho stated during Friday's press conference that he expects him to be fine at the weekend.
Liverpool's task of securing all three points at Old Trafford may have just become a lot more difficult.
