Ruben Amorim has already hinted at one position Manchester United must strengthen

The introduction of wing-backs at Manchester United has given them the change in identity that was long overdue.

In the 4-2-3-1 formation United largely became wedded to under Erik ten Hag, their football, regardless of the results, became stale, making it easy to understand why Ruben Amorim made identity the buzzword of his maiden media interview.

Despite results so far not being as positive as Amorim would have hoped for, there is no denying evidence of what he is trying to achieve has been on show. United, at times, have played some good stuff, and Amorim's system was key to stifling Liverpool in Sunday's 2-2 draw at Anfield.

United's performance against the Premier League leaders has set a standard Amorim's players must now aim to try and hit week-in, week-out. However, it remains blindingly obvious that fresh blood is needed throughout the squad.

This month's January transfer window, of course, is not the ideal time for a rebuild to take shape, and nor will it. Instead, the summer is likely to mark the first juncture for Amorim's vision to take its first meaningful leap.

Amorim's 3-4-2-1 system is very much reliant on the wing-backs. Gary Neville, following the defeat to Newcastle United, said the Portuguese head coach needs two "quite unique players" to operate on the flanks.

Amad started the Amorim era as the right-sided wing-back and quickly got to grips with the responsibilities that come with that role. However, he has started each of United's last five Premier League matches in attack, operating as
