Renovation began last June and was completed towards the end of last season. The complex reopened to the players this week.
Ratcliffe spoke at the reopening, stating: “This is one of the most recognised brands in the world.
“It stands shoulder to shoulder with Coca-Cola and Apple.
“The club has to compete at the highest level that is appropriate to the size and history of the club. While a world-class training facility won’t take us to that position alone, it is one of the key ingredients in the modern facility. Now we have one.
“When I first came to Carrington two years ago, we had a presentation here. It was clear then. It is an excellent facility. It was (leading edge) I am sure in 2000 but 25 years later it wasn’t at quite at the level it needed to be for one of the top four or five clubs in the world.
“It was the first big decision when we arrived in the first quarter of 2024, to invest in this training facility. There were lots of naysayers, who said ‘that won’t be done in 12 months’…but I am pleased to say the project has come in on budget and on time.”
