Ramon Calderon is a fan of Pep Guardiola but the ex-Real Madrid president told Omnisport Manchester City's manager can expect no guarantees.
Former Real Madrid president Ramon Calderon is looking forward to seeing Pep Guardiola and Jose Mourinho tangle in the Premier League and will not let Clasico loyalties obscure his admiration for the ex-Barcelona boss.
Guardiola's Manchester City will make the short trip to face Mourinho's Manchester United at Old Trafford on Saturday, with both men having inspired 100 per cent starts from their new clubs so far this season.
Mourinho was appointed at Madrid in 2010 to go toe-to-toe with Guardiola's all-conquering Barca side and Calderon prefers the Catalan.
