The London rivals are allegedly keeping tabs on Hull City prodigy Josh Tymon.
Both clubs have showcased their own young talent in the Premier League this season, but Tottenham Hotspur and West Ham United are allegedly looking to add another teenage to their ranks with ESPN reporting their interest in Hull City's Josh Tymon.
Spurs have developed a reputation under Mauricio Pochettino as one of the primary advocates of promoting young players into the first team, with their title push built around young stars such as Harry Kane, Dele Alli, and Eric Dier.
They also handed senior debuts to teenage stars Josh Onomah and Harry Winks, whilst West Ham have given breakthroughs to hotly-tipped star Reece Oxford and Josh Cullen.
It now appears as though they are looking to bolster their young talent with the addition of Tymon after the 17-year-old make his first steps in the senior picture at Hull.
The Tigers prospect made his debut in a FA Cup clash with Bury and also featured in a later round, starting and playing the first 55 minutes of the 0-0 draw with Arsenal at the Emirates Stadium in February.
According to ESPN, Spurs and the Hammers are both interested in the teenager's signature, whilst his impressive display against the Gunners is also thought to have piqued the interest of Arsene Wenger.
Tymon is a defender who plays mostly at left-back, and has broken into the England Under-17 set-up and could be at risk of being poached by a Premier League side, particularly if Hull are unsuccessful in the Championship play-off final against Sheffield Wednesday this Saturday.
