The pair have been strongly tipped for moves to Leeds United.
Two prospective Leeds United signings have begun following each other on Instagram.
And the pair are already acquainted on social media, despite their careers never having crossed paths.
Both Mujica and McCarron, who have already played senior football, are likely to join Leeds' Under-23 set-up initially.
But first-team additions are also imminently anticipated, with Jack Harrison, the Manchester City winger who spent last season on loan at Elland Road, and Ben White, the Brighton and Hove Albion centre-back, due to arrive on temporary deals, according to the Yorkshire Evening Post.
And the newspaper adds that Leeds hope to finalise another loan deal, for the Wolverhampton Wanderers winger, Helder Costa 'in the coming days'.
Which other players should Leeds be trying to sign in the summer transfer window?
