Former Luton Town midfielder Yaser Kasim has had his trial period with Swindon Town extended.
The 22-year-old, who began his career at Tottenham Hotspur, represented Swindon in a 3-0 pre-season defeat to Birmingham City on Wednesday.
"He looked alright on the ball, he looked very comfortable. He's started at Tottenham and he was at Brighton. He's a good footballer and worth another look," Caretaker boss Mark Cooper told Dunstable Today.
"He knits things together. He gets the ball off the back four and knits it together. He's come and not trained for a while, he's not played and he's come in and done well. You can see that he's got ability.
"My only worry is in midfield size-wise that we're not the biggest and I think we might need to look at that a little bit. He's definitely worth another look."
A number of Football League clubs are believed to be monitoring developments.
