Ketelaer back in Foals' fold
The 24-year-old striker will be happy to return to his home-town club after failing to make an impression last season at the AOL-Arena.
Ketelaer will move to Gladbach on loan for the coming season with the Foals having the option to buy him next summer.
Both clubs agreed terms at the weekend, subject to Ketelaer passing a medical in the next few days, but no details have been released as to the fee involved.
The speedy and skilful winger burst onto the Bundesliga scene during his first spell in Monchengladbach. He made 54 appearances for the Foals before sealing a lucrative move to HSV in the summer of 1999.
A series of injuries and inconsistent form, however, prevented Ketelaer from achieving his full potential at the AOL-Arena and he will now be looking for an upturn in fortunes with Gladbach.
