Ruben Amorim finally admits he made 'mistakes' at Man United as the AC Milan boss says he needs to be more adaptable in Italy

Ruben Amorim has admitted he needs to be more adaptable as AC Milan head coach than he was during his time at Manchester United.

Amorim, 41, left United in January after a torrid 14 months in charge of the Red Devils, before taking over at the Rossoneri in June.

One of the issues Amorim repeatedly complained about during his nightmare tenure at Old Trafford was that his players didn't suit his style of play, which relies on a back three. And last week, there were similar problems with the Milan squad as they lost in the Europa League to Benfica.

However, Amorim continued his unbeaten Serie A start on Sunday as Milan dispatched Lecce 3-0 at the San Siro, and showed versatility in his tactics, unlike during his tenure at United.

During the match, it seemed as though Milan's usual back three changed to a back four, with Mario Gila switching roles into the full-back position. It led to a second clean sheet of the season.

'A great victory,' Amorim said. 'I liked the movement, especially the attacking depth. We managed the game and read the opponent well.

'These are different times, but we're improving. Today the players had more freedom; in recent games we were a bit too static, stuck.

'I can't repeat my mistakes from Manchester. If we don't have the characteristics to play a certain way, we have to adapt.

'We'll go back to building with three, but we'll see. Here in Italy, the coaches are very good, especially at going after other teams one-on-one.'

Amorim has previously been criticised for stating that 2018 Ballon d'Or winner Luka Modric wasn't a fit for his system, given the quality the Croatian still possesses at 41 years of age.

The Portuguese coach still opted to start the midfielder against Lecce, though, and was full of praise for him after the match.

He added: 'With Modric, we need to have the ball for a long time, but he's ready to play every game we need.

'If we only play transition games, it's not good for him, nor for [Ardon] Jashari. In these possession-based games, he's perfect; in the others, we'll see, but he can play every game.'
