FA ban prevented Trippier returning to Premier League

Trippier's 10 week ban imposed by the FA which has been temporarily put on hold by FIFA, prevented Man Utd bidding for the player. 

United were interested in making an offer for the Atletico Madrid man, but 'The Athletic' reports that the ban made Man Utd backtrack. 

Man Utd wanted a footballer to compete with Wan-Bissaka and the man chosen was Trippier. However, the FA's decision put them off. 

That said, even if they had wanted to sign him, 'The Athletic' also says that Atletico Madrid were not going to negotiate his departure because the Englishman is a key member of Diego Simeone's squad.
