Celtic are interested in signing young Argentine left-back Francisco Ortega in the summer transfer window, according to a new transfer rumour.

The Lowdown: Summer business expected

Ange Postecoglou may still be basking in the glory of winning the Scottish Premiership title but attention will soon turn to incoming signings if it hasn't already.

The Australian will know that he has to make Celtic's squad even more formidable, ahead of what is hopefully a successful title defence and a return to the Champions League in 2022/23.

Left-back could be an area that the Hoops look to strengthen - there have been plenty of links to Iraq international Mohanad Jeahze - and a new update has emerged in that respect.

The Latest: Celtic eye up Ortega move

According to The Daily Mail's Stephen McGowan, sharing his article on Twitter, Celtic are keen on signing Velez Sarsfield defender Orteta this summer:

"Celtic looking at Argentinian U23 left-back Francisco Ortega."

Expanding in the report, McGowan says the Hoops have compiled impressive scouting reports on the talented young South American, and are also closing in on a permanent deal for Jota.

The Verdict: Great for squad depth

Ortega could be a shrewd signing by Celtic ahead of next season, acting as a strong backup option to Greg Taylor, ahead of Boli Bolingoli's expected exit.

The 22-year-old is a player who 'dominates defensively', according to South American fan site Football FV, as well as being described as a 'very all-round left-back', suggesting he would be a strong acquisition.

The fact that Argentinian giants River Plate have reportedly shown an interest in signing Ortega is a sign that he is a big prospect in his homeland, and this could yet prove to be another shrewd snip from Ange in the transfer market.
