Isaac Success is fully recovered from injury and January signing Mauro Zarate is also available for the first time having served out a suspension, Walter Mazzarri has confirmed, with Jose Holebas in contention again after a ban of his own.
Steven Defour has been ruled out for a number of weeks with a hamstring injury but new Burnley signings Robbie Brady and Ashley Westwood are in contention, though may not start.
