Carroll, 21, is a product of the Oxford United academy, but joined Brentford back in 2018.
He’s made 17 appearances for Brentford B in his time at the club, which last season saw him join Swindon Town in a short-term loan deal.
In the summer, Carroll was loaned to Carlisle United in League Two. He made 16 appearances for United before returning to Griffin park, and now the midfielder has signed a permanent deal with Stevenage, who sit bottom of League Two.
Carroll had some good performance for fellow League Two strugglers Carlisle. He’s a technical, box-to-box midfield player and one who’ll greatly bolster the Stevenage side.
Only one team will be relegated from League Two this season and as it stands, that team will be Stevenage. They’re four points behind 23rd-place Morecambe and with 16 games left to salvage their Football League status.
With one win in their last 14 though, a random 4-0 win at Cambridge United earlier in the month, Mark Sampson’s side look all but destined for the National League.

Brentford B have and are producing some fine players. They scrapped their youth academy in 2016 to create their Euro-style B team, which has a heavy Scandinavian influence with the Danish manager Thomas Frank at the helm.
Carroll will be a useful signing for Stevenage. It didn’t look as though he had a future at Brentford but with so many exciting players coming through their ranks, Brentford fans won’t be too displeased to see this move happen.
