Why? Stats are so overrated on this forum. Isla was one of the best wing backs in Europe before he joined us. You simply had to watch him play to know.
What happened? We took a gamble and bought an injured awesome player, and after a predictable bad seaaon, we're apparently selling him. It doesn't make sense to sell him now. You either admit it was a horrible transfer or else wait to see if your investment proves great.
This impatience will come back and bite us in the ass. We are willing to give Gio another chance, and have been patient with many players who are far inferior to him, so he deserves another shot. At least give him a season when he is fully fit to prove himself.
