Manchester United interim manager Ralf Rangnick believes Liverpool boss Jurgen Klopp is one of the best coaches in the world as the two prepare to come up against each other at Anfield on Tuesday night.
Liverpool come into the game against their bitter rivals full of confidence after booking their spot in the final of the FA Cup with a 3-2 win over Manchester City. United defeated Norwich City by the same scoreline at Old Trafford to boost their hopes of qualifying for the Champions League.
But Rangnick, as well as praising his compatriot Klopp, has highlighted how his side need to be at their best defensively if they are to stop a Liverpool attack that is the best in the Premier League this season.
