Sources: Spurs jet out on Thursday transfer mission for No 10 with £106m release clause

Tottenham ran the rule over Portugese sensation Joao Felix with a Thursday night transfer mission, Football Insider understands.

Scouts from the north Londoners assessed the 19-year-old attacker as he stole the show in Benfica’s 4-2 Europa League quarter final first-leg win over Frankfurt.

Felix scored a hat-trick and supplied the assist for the other goal as he provided further evidence of the talent that has had elite clubs beating a path to Benfica’s door this season.

A club source has told Football Insider that Tottenham are keeping close tabs on Felix even though his club tied him to a new contract last November that has a £106million release clause.

The likes of Liverpool, Real Madrid, Bayern Munich and Barcelona are also keeping close tabs on the Portugal Under-21 international.

Since breaking into the Benfica team at the start of the campaign, Felix has scored 15 goals and supplied seven assists in 36 appearances, with 10 of those strikes coming in league matches even though he was mainly used as a substitute up until the turn of the year.

While his primary position is as a number 10, Felix has shown his versatility by also playing as a striker or as a winger.

In other Tottenham transfer news, the club “have been sniffing around” an in-form number 10 to replace Christian Eriksen.
