Diomande ou Barcola à Anfield ?

It's the ultimate shop window: a World Cup with 48 teams - all packed with players eager to show what they can do on the biggest stage.

With the transfer window now open, BBC Sport journalists have been taking a look at some of the key names being discussed.

It's no secret that Liverpool are admirers of Yan Diomande and the 19-year-old winger made a brilliant start to the World Cup with a player-of-the-match display for Ivory Coast in their 1-0 win over Ecuador.

Diomande, who plays club football in Germany for RB Leipzig, started for his country and spent time on each flank during the 90 minutes, constantly asking questions of the Ecuador defence.

In a 2-1 defeat against Germany at the weekend, Diomande, who is valued at about £100m, played a key role in his team's goal as part of another impressive display. He is next due in action on Thursday when Ivory Coast take on Curacao.

Another attacking name linked to Liverpool is Paris St-Germain's Bradley Barcola, who started his World Cup with a goal for France against Senegal.

Just moments after coming on, the 23-year-old finished in style and he was subsequently rewarded with a start against Iraq on Monday, where he was relentless down the left wing.

Arsenal are also keen on Barcola, who may leave PSG this summer having become a back-up to Khvicha Kvaratskhelia for Luis Enrique's side.

Barcola could get his next World Cup action on Friday, when France play Norway.
