AFC Wimbledon manager Wally Downes is expecting Nesta Guinness-Walker to make a first-team impact this season.
The 19-year-old left-back had been on Chelsea and Tottenham’s books as youngster.
Guiness-Walker signed for the Dons from Met Police in May after a successful trial spell.
Asked if he could get senior minutes in League One, Downes said: “He has got to – that’s his progression.
“He did a week training with us before the end of last season and didn’t look out of place.
“He should come in and hit the ground running, the only thing that could hold him back is his inexperience. He should soon adjust to the level.” Guiness-Walker had been linked with other English Football League clubs before he put pen to paper for the Dons.
“As soon as there is a bit of interest then clubs tend to leak it out,” said Downes. “I’m not saying Met Police did that.
“But if you send your scouts there two or three times then word gets out.
“There might have been bigger clubs but it is about opportunity. Nesta came here and felt at home. He sees more chance of playing first-team football here quicker.”
Wimbledon have signed striker Adam Roscrow from Welsh Premier League side Cardiff Metropolitan University.
The 24-year-old scored 15 goals in 23 appearances as they qualified for the Europa League last season.
