Five things we learned as Manchester United defeat Southampton 1-0 in the Premier League

For the first time since February, Manchester United have won a game away from home.

In a tough fought battle, Manchester United triumphed 1-0 over Southampton courtesy of an excellent finish from Bruno Fernandes.

Here are five things UtdDistrict learnt from the victory on the South coast:

#1 Lisandro Martínez is a monster

Manchester United's £55 million summer signing was Man of the Match as United picked up a crucial win away from home at St Mary's. 

Southampton often threatened, but the Argentine was equal to everything that the Saints threw at him and alongside his other defenders helped United keep a clean sheet.

#2 United finally keep a clean sheet

United kept a clean sheet for the first time since their 3-0 home win over Brentford at the start of May, with an impressive defensive performance.

Raphaël Varane and Tyrell Malacia's introduction into the team in the last two games looks to have hugely improved the side defensively.

This spells the question: How do Luke Shaw and club captain Harry Maguire earn their spots back in this team? Regardless of the answer, the headache is a good one for Ten Hag to have.

#3 Casemiro makes debut, shows what to expect

United's new signing was only subbed on in the 80th minute, but already showed fans what to expect from him.

Casemiro did not hide his desire and intensity when defending, and in the dying minutes this already helped United as they defended a lead. His signing will have fans even more excited after today's cameo.

#4 Diogo Dalot follows on from Liverpool game with assist and strong performance

Diogo Dalot had his best defensive performance for Manchester United on Monday night against Liverpool, and continued to ride the wave of confidence into today's game.

Picking up the assist for Bruno Fernandes with an excellent cross, he arguably should've had more in a game where he showcased some excellent quality in possession.

His defensive side was also strong, he was arguably United's best player alongside Martínez. He will certainly be a key player for Ten Hag going forwards.

#5 Sancho changes wings: a tactical adaptation from Ten Hag?

The same XI started today that started in Monday night's victory over Liverpool, but there was one noticeable change; Jadon Sancho was on the left rather than the right.

Following the Brentford loss, many fans claimed Erik ten Hag should be less stubborn and learn to adapt more, after just two games in charge.

Ten Hag quickly proved his doubters wrong with his tactical setup against Liverpool, and today he switched Sancho's wing from Monday's victory. This could be a sign that Ten Hag will make plenty of minor tweaks and adaptations across the season, whilst continuing to work within his framework and this is what United need.
