Why Aston Villa set-piece coach Austin MacPhee has not been spotted on the touchline as Matty Cash SMASHES home opener against Manchester City

Set-piece coaches are a bit like Marmite; you either love them or hate them.

Either way, you certainly can’t get away from them. Whether it’s Nicolas Jover racing to the Arsenal touchline every time there’s a throw-in at the Emirates, or Brentford literally promoting their former dead-ball tactician to the top job in Keith Andrews.

Aston Villa are another side in on the act through Austin MacPhee, but he’s not been as visible of late.

Aston Villa set-piece coach Austin MacPhee has not been seen on the touchline

The Villans took the lead from a corner just before the 20-minute mark, with Matty Cash taking one touch to get the driven pass out of his feet on the edge of the box, and another to smash it beyond Gianluigi Donnarumma.

It looked like a training ground job at first glance, but there was no MacPhee on the touchline to nonchalantly take the plaudits, as figures in his role often do.

But fear not! MacPhee did make it onto the screen following Cash’s opener, along with the reason he has been out of the spotlight.

The broadcast from Sky Sports showed that MacPhee was indeed sat in the technical area, iPad at his side, with his leg in a support.

Commentator Bill Leslie later revealed that the Scottish coach has suffered a patella injury, picked up while on duty in his second role, as assistant head coach of Portugal’s national team under Roberto Martinez.

That didn’t stop him taking the limelight for just a second on Sky, his beaming smile showing exactly what he thought of his contribution to the Villans’ opener.

In FourFourTwo’s opinion, MacPhee's reaction may have been somewhat explained by Cash after the game.

"I'm going to kill Austin here," the full-back said to Sky Sports after the game. "It was a special corner, but it wasn't for me."

Whatever MacPhee's role in the goal, and wherever he's situated, Unai Emery won't mind as long as the goals keep flowing.
