Ruben Amorim has already confirmed whether Man Utd 3-4-3 experiment will end

Ruben Amorim needs results, and fast. While the optimists of Manchester United's fanbase may cling to the signs of slight improvement from last season, the bar could not have been lower. Sunday's 1-1 draw at Fulham felt like an ominous step backwards.

Amorim's 3-4-3 system has sparked mass debate since his arrival from a self-built empire at Sporting, where he applied the exact same principles to dominate Portuguese football. Rightly so, too. The 40-year-old's Premier League record is 29 matches, seven wins, seven draws and 15 defeats.

United have looked a far cry from the free-scoring team he helmed in Lisbon, managing just 33 goals in those 29 outings while conceding 44 times.

Every disappointing result amplifies cries to revert to a back-four formation, considered by many to have a more successful track record in the Premier League.

However, Amorim has strongly maintained throughout his struggles at Old Trafford that he will live and die by his way of playing football.

On December 30, after United suffered a fourth consecutive defeat during a miserable festive period, Amorim stressed: "I cannot change my idea in one day because we will lose much more now.

"So I will try to do it the way I am trying to do it. I adapt for every game - the positioning, the way the players are trying to cope without training.

"So it's really hard for them. But I maintain my idea, I want to play a certain way until the end. If I change everything now, we are going to lose everything."

In a separate interview, the United boss insisted: "Like I said, you cannot go back. We have to continue to push. Remember, we had like four training sessions altogether. So that is important.

"I know what you guys are trying to reach [for, with your questions], but it is really clear. I was here because of my idea, and I will continue to do my idea until the end."

While Amorim has no plans to abandon his three-at-the-back system, he will not be excused like he was last season.

He was thrown into the deep end at a club in turmoil on and off the pitch upon his arrival in November, with little opportunity to work on the training ground amid a congested schedule.

Now, United have completed their hierarchy restructure and are entering a new era in the club's redeveloped Carrington facility.

With no European football this term, Amorim will have the time on the training ground he was longing for. The fruits of those sessions must emerge sooner rather than later.
