Hughes said: "Robinho has had a lot going on around him. He had issues back home that needed resolving and it was about clearing his mind.
"He's back fit and well now and has trained this morning and will play on Sunday.
"He's had a period in his personal life and football life where big decisions have been made and he needed some time out. It would have been a big ask for him to play in midweek and then again at the weekend."
