The Spanish forward has been on the books at the San Mames Stadium since 2014 having joined Bilbao from Antiguoko.
And he’s turned heads while playing for their feeder team, Basconia, as well as their reserve side, Bilbao Athletic, over the past three years.
Bilbao have included Guruzeta in their squad to face United, Swansea and Celtic in the Premier League International Cup this season.
And the latest reports suggest a cluster of English giants will have the 21-year-old scouted this week.
According to The Sun, Chelsea, Arsenal and Tottenham are all going to have officials at Bilbao’s game against United on Wednesday.
And they could be joined by scouts from Newcastle United, with Rafa Benitez said to be a fan of his compatriot.
Guruzeta is out of contract at the end of the current campaign and would be available for a nominal compensation fee.
That situation’s likely to see a scramble for his signature with teams desperate not to miss out on the promising prospect.
The Sun suggest Spurs could have a secret weapon in the form of striker Fernando Llorente though.
The target man began his career with Bilbao and may be utilised to lure Guruzeta away from Chelsea‘s clutches.
Bilbao are bottom of Premier League International Cup Group D going into Wednesday’s clash.
And Guruzeta will be hoping to impress as his side look to draw level on points with second-place United.
