Tyrell Malacia says he has been driven by his healthy rivalry with fellow full-back Luke Shaw for a starting role at Manchester United.
United sprung a surprise when they moved for Malacia in the summer transfer window, with many believing the club weren't in any desperate need for a new left-back.
The 23-year-old was initially brought in as a back-up for the England international, but after impressing in pre-season, he has been given the nod by Erik ten Hag in the Premier League.
