When Marcos Rojo joined Manchester United from Sporting Lisbon for £16m, many believed that the Red Devils had made a wise investment after the Argentine’s performance in the 2014 World Cup.

Things started off well enough with the defender making 26 appearances in his first season at Old Trafford. However, there were signs of a lack of discipline when he missed a pre-season tour in the summer of 2015 due to passport issues. He was subsequently fined by then-manager Louis van Gaal.

However, he did feature pretty regularly in his second and third seasons with United, playing 41 games in total during the 2015/16 campaign. The arrival of Jose Mourinho as manager did, though, coincide with fewer first-team opportunities.

A serious knee injury didn’t help matters. He picked up an ACL in the Europa League quarter-final tie against Anderlecht; a tournament that the Red Devils would go on to win a few months later.

From there on out, Rojo’s career at United unravelled. Injuries combined with a lack of game time under Mourinho’s successor Ole Gunnar Solskjaer eventually led to a loan move back to Argentina with Estudiantes last season.

The defender was keen to stay in his homeland but a deal could not be worked out so he had to return to Manchester last summer. More fitness issues followed and he eventually got a permanent move to Boca Juniors earlier this month. The transfer fee was undisclosed so it is unlikely that United got much back on their investment.
