MILLWALL will play Spanish side Rayo Vallecano in Paul Robinson's testimonial match at The Den on July 27.
The Madrid-based La Liga club have agreed to be the opponents for Robinson's benefit game – and for new manager Steve Lomas' first home clash in charge.
Robinson told the club's official site: "I'm delighted to have this fixture for my testimonial. Rayo are a very good side and will provide us with an extremely competitive outing the week before the Championship season kicks-off.
"Not only will Lions fans have the chance to see us test ourselves against top Spanish opponents, but this will be the first opportunity for our new manager to take charge of the team at The Den, and doubtless there will be a number of new signings on view as well.
"Personally, I am working very hard on my fitness so that I can play a major role, not only in this game but in a very important season coming up for the club as well. I'm really looking forward to it, and to seeing everyone again on the eve of the new campaign."
