Maybe Robins feels with Godden only having a year left and the potential to get a fee its too good an opportunity. Sharp as a third choice offers a lot but his wage probably wouldnt give value for money
If you want to beleive its a trial thats fine but i would be amazed if Oostende had allowed him on trial before any transfer. Why risk injury to your most saleable asset befre the deal is confirmed?
Common usually when they are free agents. Cant imagine a team potentially selling a player for a million agreeing to a trial before they get the sale done
