The agreement is the second-largest in Premier League history, behind only Manchester United’s adidas deal.
‘It’s an historic day for us,’ City chief executive Ferran Soriano said. ‘What we are doing has never been done before. It is an unprecedented partnership. We needed a partner that can go fast with us.
‘This is who we are now, this is the product we can offer. Having just one partner saves times in discussions and it allows us to do things globally.
‘There are so many synergies and things that we can do together if we have the same partner. If we have one idea then we only have to talk to one person.’
Puma are already looking at signing a number of Pep Guardiola’s first-team squad, including Leroy Sane and Kevin De Bruyne.
Vincent Kompany, Sergio Aguero and David Silva are already Puma ambassadors, with CEO Bjorn Gulden claiming: ‘We have a good presence here but there will be more.’
