Sam Allardyce praises 'genius' Gylfi Sigurdsson

Sam Allardyce is seen arriving at the stadium prior to the Premier League match between Everton and West Ham United at Goodison Park on November 29, 2017 in Liverpool, England.

Everton's Gylfi Sigurdsson was the hero on Monday.

Speaking to ESPN, Sam Allardyce has paid tribute to Gylfi Sigurdsson for producing the moment of "genius" which tipped Monday's clash with Swansea in Everton's favour.

Sigurdsson left Lukasz Fabianski with no chance in the second half by bending a wonderful effort beyond the Pole from outside the box to give Everton a 2-1 lead at Goodison Park.

The Toffees killed off the clash later in the half as Wayne Rooney dusted himself down after missing a first-half penalty to score from the spot on 74 minutes.

But Allardyce was left purring over what the Iceland international did prior to that.

He told ESPN: "It's just what you need. Changes the game. You need a bit of genius. You need a bit of work from a player in the squad who can change a game and that's what we got.

Leroy Fer had fired Swansea into a surprise 1-0 lead, but Dominic Calvert-Lewin reacted quickest to Fabianki's penalty save from Rooney to slide home an equaliser.

Consequence of the win, the Merseysiders are now ninth in the Premier League, having been one point above the relegation zone just a few short weeks ago.

And if Everton can emerge from the festive period unscathed then who knows, maybe Allardyce can help the Toffees salvage something from what looked certain to be a disastrous season under Ronald Koeman earlier in the campaign.
