Carrick returned to the club in January as interim boss following Ruben Amorim's disastrous tenure, and the 44-year-old was under no pressure to deliver.
The Englishman arguably expected to stay at Old Trafford until the end of the season and be replaced by a high-profile name, but he's instead earned the job full-time.
A two-year contract was offered to Carrick earlier this week after guiding Man United back into the Champions League following 10 wins from 15 matches.
Everyone associated with the club is delighted to see that his hard work has been rewarded, but Neville has warned that being named the permanent manager comes with a "different sort of pressure" after doing a "fantastic job" as a caretaker.
"He’s done a fantastic job as a caretaker and interim but a permanent manager comes with a different sort of pressure – and a different level of expectations," Neville told Sky Sports ahead of United's clash against Nottingham Forest.
“Manchester United need a lot of players. Let’s be really clear. Michael won’t be fooled by that, nor will any Man Utd fan.
“There’s a real nucleus of five or six you can build around but beyond that there needs to be some additions that take the quality, stability and the resilience up. If you get two or three injuries in certain positions it falls apart quite quickly.
“So with Champions League next season and all of those games in midweek, they are going to need to support Michael in the summer. And I’m sure that’s what their aim is.”
United have lacked stability ever since Sir Alex Ferguson left the club in 2023, but hopefully, Carrick is the man to provide them with success for years to come.
