Cambridge United manager Jez George has urged winger Ryan Jackson to carry on improving after an encouraging performance against Guiseley in midweek.
The on-loan AFC Wimbledon man provided the assist for Luke Berry's goal in the 1-0 victory over the Lions in the FA Trophy on Tuesday night and George wants to see more of the same from the 21-year-old.
George told Cambridge News: "We want a bit more out of Ryan, because he has shown what he can do when he gets a head of steam up.
"He made a fantastic run for the first goal against Guiseley on Tuesday, we just want him to do it more often because he can be a real threat.
"We just need to keep pushing him and he needs to understand the work ethic at our club, and that will improve him."
Jackson is on loan at the Abbey Stadium until the end of the current campaign and has notched up two appearances thus far.
Meanwhile, George has explained his thinking behind the decision not to extend Brett Johnson's loan deal from AFC Wimbledon.
He added: "Brett has been really helpful for Blaine Hudson and he has done well in his month here.
"He's a good lad and a good professional who got on with it properly.
"But we'll be close enough with Michael (Wylde), although I'm not saying he'll be fit for Forest Green, and Josh (Coulson) isn't a million miles away, so it wouldn't be economically viable to take Brett for another month."
