It can be argued that Ruben Dias is one of the most important signings made during Pep Guardiola's tenure at Manchester City. However, had the manager got his way, then things might have turned out differently.
City signed Dias for Benfica in September 2020 for an initial fee of £62m, and immediately the Portugal international set about turning around City's defensive fortunes. The beginning of the 2020/21 season saw City endure their worst start to a Premier League season in years, and it quickly became obvious that defensive reinforcements were required.
Dias was signed two days after the Blues suffered a humiliating 5-2 defeat at home to Leicester. And while it took a couple of months for City to rediscover their top form, their defensive line instantly looked more soli with him starting alongside John Stones.
