Rio Ferdinand insists a hybrid of Trent Alexander-Arnold and Aaron Wan-Bissaka would be the 'ultimate machine' at right back while claiming the latter is much better defensively than his Liverpool counterpart.
Wan-Bissaka has starred at Manchester United since his £50million move from Crystal Palace in the summer while Trent Alexander-Arnold continues to go from strength-to-strength for Premier League champions-elect Liverpool.
Alexander-Arnold is widely regarded as England's best right back with a huge future ahead of him in the international team but Ferdinand believes Wan-Bissaka can fight the Liverpool star all the way for a spot in Gareth Southgate's starting line-up.
