Hughes was particularly pleased to land former Inter Milan forward Arnautovic.
"Marko is very adept at playing across the front line, "he gives us that flexibility," he told The Sentinel.
"He can play both wings, and in his own mind that is where he thinks he's more accomplished, but only because he's played more games there.
"But I've no doubt he can play in any number of positions and in different combinations with the players we've got here. In that regard, I think he's a very good acquisition.
"I'm also comfortable with the options I've got up front. I've also got Jonny Walters who can play down the middle as well."
