Jan Vennegoor of Hesselink of PSV Eindhoven (Allsport)

EINDHOVEN, Aug 22 (SW) – Celtic target Jan Vennegoor of Hesselink has told the club to up its contract offer if they expect him to move to Glasgow.

The PSV striker has been tracked by Hoops manager Gordan Strachan for much of the summer, but has revealed the move could fall apart, despite his interest in joining the Scottish champions.

"There is a big difference between what Celtic are offering and what I'm wanting," confirmed the PSV man.

"I have enjoyed my time at PSV. I have all the time in the world.

"Leaving PSV is not a necessity for me, I don't have to go and in fact part of me doesn't want to go.

"I will only go if the whole package is perfect.

"Celtic are a fantastic club with great supporters and the club has a lot of history.

"Of course it's different from The Premiership but it's all to do with your gut feeling and I have a good feeling about going to Celtic, so long as the package is good."
