Spanish clubs Valencia and Atletico Madrid are believed to be tracking Nathan Oduwa's form at Rangers.
The Sun is reporting that the La Liga duo have been alerted to the 19-year-old winger who is on loan with the Scottish Championship side from Tottenham.
Oduwa has enjoyed a bright start to his season-long spell at Ibrox and his electric performances have not gone unnoticed with suggestions that Valencia and Atletico are keeping tabs on his progress in Scotland.
