Chris Wilder and Phil Parkinson, former team-mates turned rival bosses, go head to head when Sheffield United meet Wrexham in the Championship on Friday night.
Friday night under the lights at Bramall Lane brings a Championship fixture with plenty of side stories. Sheffield United host Wrexham, and the touchline duel between Chris Wilder and Phil Parkinson is one of the main talking points.
The two managers go back a long way. They were once team-mates, and now they try to outwit each other from opposite dugouts. Familiarity at this level can be a double-edged sword. Each knows what the other values in a team: organisation, work rate and a no-nonsense approach. Neither will want to be the one who gets out-thought.
The contrast between the clubs adds another layer. Sheffield United are one of English football's proud old names, with a passionate home crowd and a hunger to climb the table. Wrexham arrive as one of the game's most talked-about stories, a club whose recent rise has put the Welsh side on the global map and into the second tier.
For both sides, points matter in a congested division where small margins shape the season. Expect an intense, physical contest, a loud atmosphere and two managers who know exactly how the other wants to play. When old friends meet in a game like this, bragging rights are on the line as well as the three points.
