Castres increase pressure

Perpignan were missing four of their first team regulars on Friday as Albi pulled off the upset of the Top 14 season so far with a nail-biting 24-23 win.

Toulouse conceded four tries against Castres including a brace from New Zealander Chris Masoe.

It means Toulouse drop to fourth place in the table, level on points with Clermont who suffered a 16-13 home reverse to Biarritz. Both sides have 36 points.

Racing Metro put the absence of the influential Sebastien Chabal to the back of their minds as they dominated the 'battle of Paris' with a 20-18 victory over Stade Francais.
