The former Tottenham and Southampton head of recruitment has been targeted by all three top flight clubs after impressing in his role at Leipzig.
However, Sky Sports News claims the Premier League trio could be forced to look elsewhere, if the 38-year-old chooses to sign a lucrative new deal, which could keep him at Leipzig until 2025.
Mitchell moved to Germany from Spurs in 2017 to become the Bundesliga club’s head of recruitment and development, but RB Leipzig are keen to tie the talent spotter down to a new long-term deal that would see him become their head of global football.
It is believed that the promotion would be likely to lead to Mitchell taking over the managerial reigns at Leipzig at the end of that new contract.
But United remain keen to tempt Manchester-born Mitchell back to his home city to become their first technical director.
