Manchester united will host Liverpool in their next FA Cup game. Even though Manchester United will be playing at home, I don't believe they will win the game. Manchester United lost their previous home game against Fulham, proving that they are currently not playing well. I believe Liverpool will win the game, even if Klopp chooses to use his academy player against Manchester united. Manchester United didn't play well at all, so their victory over Nottingham Forest to get to this round was lucky. This season, Klopp wants to win many trophies, I think with their current play they will achieve more.
Liverpool have higher chance to win that match because they are stronger and also have better form than Manchester United. The home stadium and support of fans are good support for Manchester United to beat one of strongest teams in England this season.
They will have to play against a team that want to win as many titles as possible in this season as many of their players will soon leave Liverpool and they will no longer have Klopp next season. Klopp will want to have as most successful ending in Liverpool as possible and he will try to win more titles in his last season with Liverpool.
Newcastle performed well from the beginning of the season as well, but as the Champions League games started, the way they performed decreased, the majority of their players began suffering from injuries. However, Newcastle qualified for the Champions League, they had a very strong performance last season, their present form is very different from last season. Currently at 10 position, Newcastle continues to struggle to win their games.
Newcastle United focused too much on Champions League and they actually created good impression there. They finally failed to go to a round of 16 and returned to Premier League with lot of negative effects. Their bad performances in Premier League are partially caused by their ambition to fight in Champions League. FA Cup is where Newcastle United can get a trophy and heal this failed season.
