#2 Attack from the right
With Anthony Martial and Marcus Rashford occupying the left wing on every line-up, the club has failed to replicate and spread the attack from the other side of the pitch. It's understandable due to both Martial and Rashford being right-footers who love to cut in and shoot/cross but it's also counterproductive given defences know where to remain the strongest.
And this is affecting Manchester United on the counter with 20% of the goals they've conceded being created from the opposition's left wing – the opposite wing of where Martial and Rashford operate on.
Should Manchester United put the opposition left-back under equal pressure, it also forces the other team to counter on the same side of the pitch making United's job a little easier dealing with counters.
