One of the most intriguing games of the weekend takes place at the Riverside on Saturday lunchtime (12:30 BST) as a fairytale start and a nightmare start converge.
New boss Rob Edwards' Middlesbrough have won all three games and sit joint-top of the early Championship table with Stoke whereas Ruben Selles, the new man in the Sheffield United dugout, has overseen three defeats to leave the Blades bottom of the table with only pointless Oxford United for company.
Middlesbrough are unbeaten across their past eight home league games against Sheffield United (W6 D2), keeping six clean sheets across that stint since a 2-1 defeat in October 1997.
