Harvey Barnes can become one of the best players in the country as long as he stays injury free, according to Leicester manager Brendan Rodgers.Barnes signed a new four-year deal with his boyhood club on Thursday after a superb 2020-21 campaign in which he scored 13 times in all competitions and made his England debut before a knee injury cut short his season. And Rodgers feels there is more to come from the humble 23-year-old, who has been at the club since he was eight.Hes obviously had wonderful support from his parents and the club and both of those have always looked to develop his talent, Rodgers said ahead of Mondays Premier League game at West Ham.I believe hes going to become a really, really top player in these next few years.When I came in you could see the talent but he needed to score more goals and week by week he started to do that.Unfortunately we missed him an awful lot at the tail end of last season but hes come back, hes getting fitter and over the next few years hes going to turn into one of the country’s top talents.I think the only thing that will stop him will be availability. If he can stay injury-free, get that little bit of luck, you can just see his game coming together.Hes got that hunger and is gaining confidence all the time. Whats great about Harvey is hes a very humble boy, he doesnt get carried away with it. He comes in with a wonderful attitude.Im absolutely delighted hes re-signed, I think hes enjoying it here. Hes a really clever boy, very coachable, and hes hungry to be the best player he can be and thats the type of player and person you want to work with.Subscribe for free to TEAMtalk’s daily newsletter…Rodgers was also full of praise for veteran striker Jamie Vardy after the 34-year-old scored the winner against Wolves on the opening day of the season.Hes a brilliant player, Rodgers added. He looked great over pre-season, went into the game last week and his running, his penetration, his pressing everything whats good about Jamie was there.And that opportunism, how he reads it, gets across the post and gets that touch and finish was sensational, so hopefully many more of them goals over the course of the season.Leicester remain without Wesley Fofana, Jonny Evans and Ryan Bertrand for their trip to the capital.Fofana suffered a fractured fibula during a recent friendly against Villarreal, while Evans is still recovering from a foot problem as he targets a return after next months international break.Bertrand is ruled out after testing positive for Covid-19 ahead of the game against Wolves, but Timothy Castagne is available following an eye injury.READ MORE: Newcastle pushing for Leicester man, but transfer dependant on initial exits
