David Moyes and Jose Mourinho met for the first time since their summer appointments at Manchester United and Chelsea respectively in an intriguing early season clash of two title heavyweights at Old Trafford.
Both managers made big calls with Moyes recalling Wayne Rooney after a summer of speculation linking him with Chelsea. Mourinho made the bold decision to leave Juan Mata on the bench and play without a recognised frontline striker.
TACTICS:United had good shape with Rooney drifting around behind Robin van Persie and they showed desire to piece together quick moves. Chelsea looked to the likes of Oscar and Eden Hazard to drive them forward but the safety-first defensive approaches of both sides prevailed.
SUBSTITUTIONS:Bringing on a striker in Fernando Torres indicated a change of emphasis from Mourinho and the Spaniard immediately wanted to run at defenders. But he too was well dealt with by the United defence. Moyes' substitutes - Ashley Young and Ryan Giggs - also did little to affect the game.
VISIBILITY:While Moyes tended to come and go on the technical area, Mourinho was on his feet a lot more. The Portuguese erupted in fury after a series of decisions went against his side and he sarcastically waved to the United fans after receiving some abuse.
OVERALL IMPRESSION:The pair showed their respect for each other by hugging prior to kick-off but at the start of what could be an intense rivalry, neither wanted to give an inch. It was a scoreless draw on the field and probably one off it too, with neither really gaining an edge of the other.
