Crystal Palace and Brighton are chasing Slovakian goalkeeper Dominik Greif ahead of the January window after his masterclass at Wolves, Football Insider understands.

The Premier League duo made a transfer mission to Molineux to watch Greif in action for Slovan Bratislava against Wolves in the Europa League.

Sources at the two clubs have told Football Insider that Palace goalkeeping coach Dean Kiely and Brighton’s assistant goalkeeping coach Casper Ankergren were sent to cast an eye over the 6ft 6in giant.

The 22-year-old impressed in his side’s late 1-0 defeat at Molineux, with his display including a save from Ruben Neves’ penalty in the game.

The scouts fed back favourable reports on Grief, who has kept nine clean sheets in 24 games so far this season.

Ex-goalkeeper Nuno Espirito Santo, the Wolves manager, was fulsome in his praise of Greif after his performance against his side last week.

He has broken into the Slovakia national team this season and is regarded as one of the best young goalkeepers in Europe.

Palace and Brighton are both looking to strengthen their goalkeeping options and they are set to continue to monitor Greif ahead of the January transfer window.

The Selhurst Park number one is Vicente Guaita, while experienced Wales international Wayne Hennessey is his deputy.

At Brighton, the first choice this season has been Matthew Ryan, who has started all 12 of their league matches.

In other Wolves news, it can be REVEALED that the club are in advanced talks to agree new deal by the end of December.
