LONDON, England -- Norwich City and Southampton both threw away two-goal leads to deepen their relegation fears, while Bolton Wanderers moved above Liverpool into fifth place in the English Premiership on Saturday.
Bottom club Norwich led 3-1 at second-bottom Crystal Palace before goals by Michael Hughes and Andy Johnson, with a disputed late penalty, secured a 3-3 draw for the home team.
Third-bottom Southampton led 2-0 at home to Aston Villa but lost 3-2 after a second-half fightback by Villa.
The results meant Norwich, with five games left, stayed bottom on 24 points, with Palace on 27, the same as Southampton and one point behind West Bromwich Albion who did not play.
Senegal striker El Hadji Diouf scored Bolton's winner in a 2-1 victory at Charlton Athletic, a result that lifted them a point above his former club, Champions League semifinalists Liverpool, who drew 2-2 with Tottenham Hotspur at Anfield.

In a dramatic match at Selhurst ParkPalace went in front through Finn Joonas Kolkka but Dean Ashton struck twice to put Norwich in charge.
When Leon McKenzie made it 3-1 eight minutes into the second half Norwich looked on course for their first away league win of the season.
But Hughes's diving header gave Palace hope and Andy Johnson earned and converted a controversial spotkick seven minutes from time to deny the visitors.
Kevin Phillips and Peter Crouch put Southampton 2-0 up against Villa after only 13 minutes but second-half strikes by Carlton Cole, Peruvian Nolberto Solano and Steven Davis floored Harry Redknapp's side who defended appallingly.
Gerrard woe

Luis Garcia leveled for Liverpool before half-time only for Robbie Keane to restore Spurs' lead.
After Gerrard blasted his spotkick wide Finnish defender Sami Hyypia volleyed in the home team's second equaliser after 63 minutes.
Liverpool, who overcame Juventus to reach the last four of the Champions League on Wednesday, have 51 points, one fewer than Bolton and three fewer than fourth-placed Everton who have a game in hand.
Diouf's neat headed finish gave Bolton the points at The Valley after Charlton's Francis Jeffers had equalized Jay-Jay Okocha's opener for Wanderers.
