Tottenham have tabled a formal bid for Holland striker Vincent Janssen, according to a report.

Dutch publication AD claim the north Londoners’ opening offer for Janssen has been rejected by his club AZ Alkmaar.

The size of the bid is not stipulated but reports in Holland have claimed the Eredivisie club are asking for around £12million for Janssen.

As reported by Football Insider, Spurs held talks with the AZ Alkmaar spearhead in London a fortnight ago as they pressed ahead with plans to strengthen their attack this summer.

The Holland international has been targeted on the back of his performances for club and country after an outstanding 2015-16 campaign.

The 21-year-old was the top scorer in the Dutch League this season with a virtual goal-a-game haul of 27 goals in 34 games. In all competitions, he struck 32 times in 49 matches.

The Holland spearhead has also scored three goals in five international appearances even though he only made his international bow in March. He scored the equaliser from the penalty spot in the recent friendly against England at Wembley and netted the opening goal in the 2-0 win over Austria earlier this month.

Janssen has made it clear that he wants to play in the Premier League and is open to the possibility of a transfer this summer.

“I want to make a step, that is clear, but there is no white smoke just now,” Janssen said, as quoted by the Mirror. “England? We will see. Maybe something will happen in the holidays. I will take my phone with me anyway.”

Mauricio Pochettino is keen to beef up the Spurs attack after Harry Kane led the front line virtually singlehandedly in the recently completed domestic campaign.

As revealed by Football InsiderMarseille spearhead Michy Batshuay has been extensively scouted by Pochettino’s recruitment team this season.

In other Tottenham transfer news, another White Hart Lane attacker is set to be sold this summer after a decision by Pochettino.
