Manchester City boss Pep Guardiola said he expects a tougher challenge from Manchester United following British billionaire Jim Ratcliffe's purchase of a minority stake in the club.
However, the City boss said he intends to keep his club at the top of the Premier League for as long as possible. Ratcliffe, who has taken a 27.7 percent stake in United and will have control over football operations, said he wants to knock City and Liverpool "off their perch" within three years.
United have not won the Premier League since former manager Alex Ferguson retired in 2013, while City have become the dominant force in English football.
Ferguson famously spoke in similar terms in his early days as United manager in the late 1980s when Liverpool were the dominant force.
