Nottingham Forest, Derby County, Birmingham City, Charlton Athletic and Bristol City are reportedly interested in Perry Ng.
Birmingham City, Charlton Athletic and Bristol City are also reported to be looking at signing the 23-year-old defender.
According to WhoScored, Ng has made 32 appearances in League Two for Crewe so far this season, scoring one goal and providing five assists in the process.
The defender has also played four times in the FA Cup and twice in the EFL Cup this campaign, according to WhoScored.
Advantage Nottingham Forest?
While Derby, Birmingham, Charlton and City all will be tempting for Ng, Forest probably have a major advantage over them all.
Forest are going strong in the Championship at the moment, and the Reds could clinch automatic promotion to the Premier League, meaning that they would be very appealing to Ng.
