Manchester United have made a new offer for Ajax defender Matthijs de Ligt.

Sport says United have "significantly improved" their offer to tempt a player who has already become one of the stories of the summer transfer window.

This follows reports optimism at Barca had dwindled over the signing of De Ligt, who could join his Ajax teammate Frenkie de Jong at the Nou Camp next season.

The teenager has reportedly already rejected a proposal from United, who are desperate to revamp their squad this summer following a disappointing campaign which featured them missing out on the Champions League for 2019/20.

United are now "one of the top contenders" to sign the centre-back, although that has arguably always been the case.
