Chelsea and Manchester United launched the English season in explosive fashion as the Bluesâ€™ 4-1 penalty shoot-out win in Sundayâ€™s Community Shield was marred by an ugly clash between Michael Ballack and Patrice Evra.
With United keen to prove a point to the critics questioning their ability to cope without Cristiano Ronaldo and Carlos Tevez and Chelsea trying to impress new boss Carlo Ancelotti, there was a definite edge to a match that finished 2-2 after 90 minutes.
The bubbling tension boiled over in the second half when United defender Evra fell to the Wembley turf in pain after a cynical body-check from Chelsea substitute Ballack.
Referee Chris Foy waved play on but Unitedâ€™s players wanted Chelsea to kick the ball out so Evra could get treatment.
Chelsea refused and Frank Lampard took advantage to score, much to the frustration of Evra who became involved in a row with Ashley Cole and then scythed down Ballack to earn a booking.
Sir Alex Fergusonâ€™s team had taken an early lead when Nani drove home from the edge of the area. Ricardo Carvalho equalised after half-time before Lampardâ€™s controversial strike, but Wayne Rooney levelled for United in stoppage time.
