Testimonials were a thing when players earned about the same as a High St Bank Manager. It gave them a retirement nest egg. Don't think top flight modern players need that any more. Would be nice to thank him for his service though since many have gone without any real recognition.
He definitely deserves some recognition and suspect we will do something at the last game of the season although not sure whether that would be decided by that Brentford game (If no testimonial although I would hazard a guess that the money would go to charity)
