The 22-year-old signed from second-tier side Almere City last summer and went on to finish up as the Eredivisie’s top scorer during his debut top flight campaign, notching up 27 goals in 34 appearances.
Tottenham Hotspur have been heavily linked with the Netherlands international ahead of the summer window amid their search for a dependable understudy to star striker Harry Kane.
The England international started all 38 of the Lilywhites’ Premier League fixtures last term and lead the line for his country at Eur 2016 – an enormous physical burden on a 22-year-old.
In fact, Spurs are believed to have already seen a bid for Janssen, who boasts three goals in five outings for his country, rejected by AZ Alkmaar.
And the 5 foot 11 front-man has now hit out as his club for rejecting the north London outfit’s offer, claiming he’s already made it clear he wants to leave this summer.
According to RTVNH, Janssen said; “I have expressed my choice to the club. In my opinion, Spurs bid a high amount. At the moment I’m still a bit disappointed with AZ. I’m disappointed with how they behaved.”
He continued; “I indicated I would take the next step and want to get away from the club. They know and are aware of. It’s a shame, I would have wished that it would go a little faster.
“Sure it’s fine to train again. AZ is a fantastic club but I want to make that next step for my development. Ultimately I hope to shake people’s hand here and walk out of the door on good terms.”
