Ruben Amorim's tenure as Manchester United boss has begun with concerns over the lack of intensity shown by players during his initial training sessions.

The Portuguese tactician, known for his high-energy approach, has already set about implementing his preferred 3-4-3 formation but has encountered early challenges in reshaping the squad's mindset.

Amorim was reportedly particularly disappointed with the efforts of players not selected for international duty, noting a need for increased pace and commitment in training.

The absence of many top players due to international fixtures has further complicated his efforts to instil his tactical philosophy, leaving the manager reassessing the scale of the challenge ahead.

United's poor league position adds to the pressure. The team currently sits 13th in the Premier League, with just four wins from 11 matches, though they remain only four points behind fourth-placed Arsenal in a congested table.

Amorim's first test comes on Sunday against Ipswich, a match that offers an opportunity to make an immediate impact.

However, reports suggest he has already identified players who may not fit into his long-term plans, signalling potential changes ahead.

Fans will hope Amorim's dynamic vision and tactical expertise can revive the Red Devils and restore their competitive edge.
