Stevenage have terminated the loan of Watford midfielder Josh Walker, but boss Graham Westley says he hopes to strengthen his side this week.
Walker, 22, failed to make a start during a spell that was initially set to conclude in January.
"It hasn't quite worked out and he's gone back, which is the best thing for everybody," Westley told BBC Three Counties Radio.
On a new signing, he added: "We'll see something happen after the weekend."
Speaking after Saturday's 0-0 draw at Leyton Orient, the Boro manager continued: "The lads are doing well after promotion. They're learning their new level and they're starting to acclimatise.
"We showed today we haven't got quite enough in the camp to win on a consistent enough basis.
"So we're looking to add a little bit of strength here and there. You bring in quality players and others will start to learn and raise their own level."
Walker, who was in his second loan spell at Stevenage, returns to Vicarage Road after making six substitute appearances.
"It didn't really work out how Josh or I would have liked," said Westley.
"He's got a lot of talent as a footballer. I knew he wasn't going to walk straight into the side. I was hoping he was going to develop and evolve and give us another option down the right-hand side."
