Mourinho and Guardiola remain best of enemies

Not many people talk badly of Pep Guardiola, a sainted figure in soccer, but Manchester City's manager will find two of his most vocal critics facing him down at Old Trafford on Saturday.

While Spain is a world away from Manchester on a dreary day, the fallout from Guardiola's combustible relationship with Zlatan Ibrahimovic, whom he managed for an ill-starred season at Barcelona, and Jose Mourinho, whom he opposed in 11 'El Clasicos', is impossible to ignore, particularly since all three descended on English soccer's second city.

Ibrahimovic's spell at the Nou Camp ended with him branding Guardiola a "spineless coward" for speaking to him only twice in six months.
