Sydney van Hooijdonk to Celtic transfer rules are already set as striker price crash follows Bologna boss spat with dad

Celtic are reported to be tracking striker Sydney van Hooijdonk - and a lowball offer could seal a move to the Scottish Premiership this summer.

It follows a public spat between his dad and former Hoops' hero Pierre and Bologna boss Thiago Motta after he returned to the Serie A side off the back of successful loan spell at Heerenveen. Reports in Germany suggest that a return of 16 goals in 32 games last season has caught the eye of the Scottish champions and Bundesliga outfit Wolfsburg with the clock ticking down the transfer deadline.

But that form left Bologna boss Motta unimpressed and he did not include the 23-year-old in the pre-season training camp in Spain - freezing the frontman out of the first-team picture immediately. Motta, who took over at the Italian outfit midway through last season, irked dad Pierre who took and his decision to leave Sydney out of the camp without seeing him up close.

He hit out in the Dutch press stating: "It is incomprehensible that such a decision can be taken without anything motivating it. I don’t think Sydney could ever have created problems for the coach. I say: take him to the retreat, so you can judge him properly and protect the value of the player.”

Motta was asked about the situation of Van Hooijdonk Jr following the outburst - and only pointed the forward to the exit door. He said: "He has to find another situation for himself.

"I’m happy with how he trains. He always gives his best. But that doesn’t alter the fact that he has to go and play continuously."

And following the row, Bologna have reportedly dropped their valuation in an effort to offload the centre-forward before the transfer deadline. VI claim that the Serie A side had set the asking price at €8million
