Alexis Mac Allister introduced himself to the Premier League today – and ensured a degree of justice was done at Selhurst Park.

Albion arguably deserved to win at Crystal Palace rather than draw 1-1.

They certainly had the possession, the poise and the promising situations from which to have done so.

But they may well have ended up empty-handed without the Argentinian’s first goal in the Prem.

The sub let fly from the edge of the box and his shot flew past Vicente Guaita, seemingly with a slight deflection en route.

Mac Allister has played before in the top flight, though not this season.

But this was his first headline-grabbing moment for the Seagulls and underlined a goalscoring instinct we have seen in the Carabao Cup.

It was a hard-earned point and it came at a cost.

Albion’s ambition to win the game led to a corner from which Lewis Dunk’s lunge brought a red card which will rule him out of visits to the Amex by West Brom and Burnley as well as a trip to Tottenham.

The Seagulls could have no complaints about that decision by Stuart Atwell but plenty about his call which left them chasing the game.

Michy Batshuayi went down dramatically as a cross dropped at the far post – and Wilfried Zaha put away the spot kick.

Sky pundit Darren Moore, a battle-hardened centre-back in playing days, felt Attwell had no option but to point to the spot because Tariq Lamptey had hands on Batshuayi's back.

He was probably in a small minority who saw it that way.

Albion were in control up until then and resumed command in the second half.

A lack of killer instinct cost them, both before and after the Zaha spot kick - until Mac Allister seized his moment.
