Celtic are targeting a deal for Paris Saint-Germain midfielder Edouard Michut.
A report has it that the Scottish club are preparing an offer in the region of £2m (€2.5m) for the 19-year-old.
Michut is a France U19 midfielder who has been impressing in PSG’s academy – but he has also played six times for PSG in Ligue 1 and twice in the Coupe de France.
He was in and around the first-team squad last season and also scored twice in eight appearances in the UEFA youth league.
Reports in France at the end of the season claimed he has become frustrated at the lack of a pathway into the first team at the Parc des Princes and is looking to leave this summer.
The Scottish Premiership champions have already made five additions headlined by the signing of impressive winger Jota on a five-year deal from Benfica for £6.5m following his successful loan spell last season and right-back Cameron Carter-Vickers in a four-year deal from Tottenham.
Lanus left-back Alexandro Bernabei has also joined in a move worth £3.75m along with Dundee United goalkeeper Ben Siegrist and forward Daizen Maeda from Yokohama.
But manager Postecoglou, who led Celtic to the title and League Cup in his first season in charge, is desperate for his side to improve and for the squad to strengthen.
