Alexis became the first Chilean to play a competitive game for United after moving from Arsenal in January 2018, with Henrikh Mkhitaryan heading in the opposite direction.
The 31-year-old scored five goals in 45 appearances for the Reds, with highlights including two assists in the remarkable 3-2 comeback win away to Manchester City in April 2018, the opening goal in our 2-1 Emirates FA Cup semi-final win over Tottenham Hotspur at Wembley, later that month, and the first goal in the 3-1 FA Cup victory over his former club Arsenal at the Emirates in January 2019.
