|Guinness Pro 12: Glasgow v Scarlets|
|Venue: Scotstoun Date: Friday, 9 January Kick-off: 19:35 GMT|
|Coverage: Live on BBC Two Wales, BBC Radio Wales, BBC Radio Cymru, BBC Alba and the BBC Sport website|
Scarlets centre Scott Williams says they can rise to the Pro12 top four if they can reproduce the performance that saw them beat table-topping Ospreys.
"I think we wanted it more. I think it showed. We had a little bit of an edge to us," said Williams.
He added: "If we keep putting performances in like that... we've got a good chance of finishing top four."
Injury forced Williams to miss their 17-15 defeat at Liberty Stadium on 27 December.
He returned at Parc y Scarlets to lead the Llanelli-based team to a first win over Ospreys since 2011.
Seventh-placed Scarlets travel to Glasgow, who lie second, in the Scrum V Live game on Friday, 9 January.
The west Wales region are eight points off fourth-placed Irish province Leinster and 12 points below Ospreys.
"Our home record's good… but we've got to start winning our games away if we want any chance of getting something out of this league," said Williams.
"[It's] a big week and it's a big game for us next week, Glasgow away.
"If we play like we did against Ospreys, then we've got a good chance."
