The Scotland international is out of contract at the end of the season, which comes with Sunday's game at home to Manchester United, and it has been widely assumed he will be moving on.
"He's played a lot of games in the second half of the season, he's done really well and he's happy," the Albion boss said. "I will talk to all my players at the end of the season and make sure where they are and let them know where I am.
"His situation hasn't changed from what I said before. His biggest gripe in the first half of the season was that he didn't play enough. The second half of the season, I don't think he can have that complaint. That's where it is."
