Apparently everyone was. Ipswich, QPR, you guys, etc. When everyone delved deeper it became apparent that he was very one dimensional and too predictable. When all the scouts continued coming after his drop in form it turned out they were watching Harlee Dean and Simon Moore.
I do think Forrester could have done better than Doncaster Rovers though. I imagine they'll struggle in The Championship and will revert to their long ball game that featured heavily in their final two seasons in that league - not ideal for a ball-playing winger. He has small issues with fitness and injuries though, so it'll be interesting to see how he does. Wish him all the best though.
