Who gets the nod in Jonathan Woodgate's first choice Boro defence?
The manager has been forced into changes in his backline in the first few weeks of the season, with both Hayden Coulson and George Friend battling injuries.
He's alternated betweem Anfernee Dijksteel and Jonny Howson at right-back.
And at centre-half, he'll soon have Dael Fry ready and available.
So who will play?
And will it be a back four or will the head coach be tempted to tinker with the shape?
That's on the agenda for our latest Tripe Supper Boro podcast, as Dominic Shaw is joined by Philip Tallentire. For information regarding your data privacy, visit acast.com/privacy
