The question is what level Ruben can play at, which may the determine the size of bid coming in for him. I’d say League 1, though are still question marks about his stamina. Correct me if I’m wrong, but I don’t think there are many signings made for over a few hundred grand at that level, and even then there aren’t many clubs with those funds.
The nightmare scenario would be if someone like Wrexham or Stockport came in with a decent bid. Or Mansfield.
