Jason Cummings joined Nottingham Forest from Hibernian in the summer transfer window.
Cummings joined Forest in the Championship in England from Hibernian in Scotland in the summer transfer window.
According to Sky Sports, the Reds had to pay Hibs a transfer fee in excess of £1 million in order to secure the services of the Scotland international.
The 22-year-old striker has failed to make a massive impact at Forest, having managed just one goal in seven Championship starts so far this season.
Forest manager Warburton has admitted that it has been hard for Cummings to adjust to the Championship in England due to the stronger and bigger defenders, but the former Rangers boss is confident that the young striker will eventually come good.
Warburton told The Scottish Sun: “Jason was always a player I admired when I was Rangers manager.
“It’s been a bit harder for Jason to adjust, but I’ve no worries about him. With respect to defenders in Scottish football, in the Championship they are bigger, faster and stronger.
“Jason just needs time, but we beat Newcastle at St James’ Park in the League Cup and he scored twice. He was superb.”
Cummings is a good striker who did well during his time at Hibernian, and Forest fans should be optimistic that youngster will eventually come good at the City Ground.
Forest are 11th in the Championship table at the moment with 30 points from 21 matches, seven points behind sixth-placed Sheffield United.
