Bert van Marwijk has warned former club Feyenoord against signing Manchester City striker John Guidetti this summer.
The 23-year-old, who is currently on loan at Celtic, is reportedly a transfer target for the Dutch side where he spent a year earlier in his career.
However, Van Marwijk is not all that convinced by Guidetti's ability, and believes that it might be a better choice to look elsewhere.
"With Guidetti you just have to wait and see," he told Studio Voetbal. "That boy has long been injured, doesn't always play at Celtic and the second time at a club is always difficult."
Ex-Netherlands coach Van Mawijk has previously spent five years at Feyenoord across two spells as manager.
