Middlesbrough and Watford both make two changes for this afternoon's Premier League clash, with Isaac Success among the Hornets' starters for the first time.
Isaac Success has been handed his first Watford start in one of two changes for the Premier League clash with Middlesbrough at the Riverside Stadium.
Miguel Britos is the other player to come in from the 2-2 draw with Bournemouth two weeks ago, with Juan Zuniga and Troy Deeney dropping down to the bench.
Britos has been struggling with a knock picked up recently, while Valon Behrami was also a doubt for today's match but is deemed fit enough to start in midfield.
The hosts also make two changes from their last outing, a 1-1 draw against West Ham United, as Gaston Ramirez and Alvaro Negredo return to the starting lineup.
Viktor Fischer and Jordan Rhodes are the men to make way, with Christian Stuani named among the starters after returning from international duty with Uruguay unscathed.
Boro are seeking a first win in five against Watford this afternoon, three of which have ended in defeat.
Middlesbrough: Valdes; Barragan, Chambers, Gibson, Friend; De Roon, Forshaw; Stuani, Ramirez, Downing; Negredo
Subs: Guzan, Ayala, Bernardo, Clayton, Fischer, Rhodes, Traore
Watford: Gomes; Kaboul, Prodl, Britos; Amrabat, Capoue, Behrami, Holebas; Pereyra, Success; Deeney
Subs: Pantilimon, Mariappa, Kabasele, Zuniga, Watson, Guedioura, Ighalo
Mazzarri happy with Watford character >
