Premiership leaders Chelsea needed a second-half fightback to draw 1-1 at Everton in the FA Cup while league one Brentford pulled off the shock of the fourth round when they beat Sunderland 2-1 on Saturday.

Everton deservedly went ahead with a 36th minute James McFadden header but it was all Chelsea after the break and the champions secured the replay with a 73rd-minute Frank Lampard shot.

Dudley Campbell got both Brentford goals to pour on the misery for Sunderland, eight points adrift at the bottom of the top flight.
 
Middlesbrough and Birmingham City face replays after being held to 1-1 draws by second division opposition - Coventry City and Reading respectively - but third division Leyton Orient, who knocked out Fulham in the third round, suffered a last-gasp 2-1 defeat at east London rivals Charlton.

There was an upset win for league one Colchester, who beat second division Derby County 3-1. West Ham United beat Blackburn Rovers 4-2 and Manchester City overcame Wigan Athletic 1-0 in two all-Premier games.
 
Cup holders Arsenal are playing later this evening, away to Bolton Wanderers. Last season's runners-up Manchester United visit Wolverhampton Wanderers on Sunday.
