Charlton Athletic forward Lyle Taylor has reportedly emerged as a transfer target for Rangers.
While Taylor is regarded as a key man at The Valley, the 29-year-old has just over six months remaining on his contract.
Unless fresh terms are penned before the end of January, the Addicks must decide whether to cash in on the frontman or risk losing him on a free transfer in the summer.
According to Sky Sports News, Rangers are considering whether to try to take advantage of the situation as they think about making additions at the beginning of 2020.
Despite Alfredo Morelos and Jermain Defoe being regarded as first choices at Ibrox, Steven Gerrard may look to boost his options in the final third.
West Bromwich Albion, Sheffield Wednesday and Swansea City are also said to be monitoring the situation.
