Southampton are back on the trail of Colombia midfielder Juan Quintero.

The Porto midfielder is on loan at Rennes and Southampton posted scouts to watch them in action against Paris St Germain last Friday.

Quintero played 66 minutes and was replaced by Kamil Grosicki with the score at 0-0 but a late goal from Angel di Maria gave PSG the win.

Koeman will look to bolster his squad with the potential arrival of Quintero seen as providing added competition

A 22-year-old playmaker, who can also play on either wing, Quintero is regarded highly by Ronald Koeman who has been aware of him for the past year and tried to sign him last January.

Porto signed him for just £4m from Pescara but he is valued around £16million and has 13 caps for his country. He was part of their 2014 World Cup squad, scoring against Ivory Coast in the group stage.

Southampton are currently seventh in the Premier League after a 2-0 win over Bournemouth at St Mary's on Sunday.
