Good luck to him. I wonder if the 'option to buy' includes a fixed price? It would be nice to think a successful season for him could earn us a few quid more, but I suspect the price (if they want him), is already set?
Also, this says good things about Digne, whose seen the new manager bring in competition for his place, and has seen him off, despite all the signs being he'd be the one to leave last summer. Hopefully he and Maastsen can push each other to new heights this season!
