Dorrans saw multiple offers from West Ham United turned down by Albion before penning a new contract.
He told The Herald: "It's been tough, but I thought we handled the away games pretty well.
"We were disappointed after the Liverpool game and that shows how far we've come since last season. I've still got a long way to go in the game, I'll keep learning. Everybody wants to play at the highest level, so I want to play for big clubs and get as many caps as I can. Who doesn't want to do things like that?"
