If Guardiola does take the Manchester City job next season, here is some heads-up for what awaits him.

Guardiola, the former Barca coach, will renew his rivalry with Chelsea manager Jose Mourinho, who used to take the helm of Real Madrid, in a repeat of El Clasico adversity.

In Manchester derby, Guardiola will reunite with former mentor Luis van Gaal, current United manager. The triumvirate of Van Gaal, Guardiola and Mourinho will form a bond with their Spanish La Liga experiences.

Manchester City is generous on transfer spending, because they want more than a Premier League title they have conceded to Chelsea this season. Guardiola has to weigh Champions League on his back

It remains questionable whether Guardiola can adapt his exquisite tiki-taka tactics to a more fierce, straightforward playing style in England, which hasn't changed much though an increasing of influx of Spanish and Portuguese-speaking players have added subtlety.

Despite the all-winning "dream team" the Catalan created in Barca, skeptics insist that he wouldn't be so successful out of the club. The City job can be a chance for Guardiola to prove himself.
