Yan Diomande showcased the talent that has made him a Premier League transfer target before Amad Diallo scored the only goal of the game to help Ivory Coast beat Ecuador 1-0 in their World Cup group E opener.Ecuador hit the crossbar twice in the first half, first through John Yeboah and then via Alan Minda before Ivory Coast’s Elye Wahi hit the same crossbar at the start of the second half.Ecuador are 25th in FIFA’s world rankings and have been spoken of as potential dark horses at this tournament but it was Diomande, the RB Leipzig forward wanted by Liverpool, who made the greatest impression with his electric wing play.The winner came from substitute Amad in the 90th minute, with Ivory Coast now second behind Germany, who won 7-1 against Curacao.Here The Athletic’s Jack Lang and Jacob Whitehead break down the key talking points.Is this why top teams want Diomande?How do you beat a brilliantly organised and physically strong defence? There are very few answers, but the most reliable is to win one-vs-one duels — one of the reasons why skilful wingers have come back into fashion over recent years. Look at Manchester City, and their transition towards take-on merchants of Jeremy Doku and Rayan Cherki.Well, Ivory Coast were faced with this problem in Philadelphia — but fortunately boasted one of the most-exciting dribblers in world football in 19-year-old Yan Diomande, who boasts the highest take-on success rate of any winger in Europe. The Athletic reported earlier this month that Liverpool had made contact with RB Leipzig over his potential transfer, to be quoted a price in excess of €130million (£112.4m, $151.2m).Diomande was playing for DME Sports Academy in Florida just over 18 months ago — now, back on the east coast, he was starring for Ivory Coast at the World Cup, at the centre of everything his nation did well. It is clear why Liverpool — as well as a host of other top clubs across Europe, including City themselves — retain an interest in the teenager.
