Man Utd news: Jose Mourinho is better than Pep Guardiola because of Chelsea

Guardiola led his side to a record-breaking title win last term, becoming the first team in the Premier League era to reach 100 points in a single campaign.

They also won 32 games in the competition – also a record.

Mourinho, meanwhile, has struggled at Manchester United to mount a serious title challenge in his two years in charge, despite finishing second last year.

But when asked which of the managers has had the biggest influence on English football, Merson still backed the Portuguese.
