The Maritimo defender is set to join the Championship side.
Now they are aiming to get another unknown through the door with the hope he could have a similar impact. The club are, according to Portuguese source Record, on the verge of signing German centre-back Patrick Bauer from CS Maritimo.
Bauer, a former Germany under-20 international, is a former VfB Stuttgart youngster and is highly rated in Portuguese football.
His performances have attracted the interest of plenty of suitors this summer. At the start of the month Kicker reported that Aston Villa were also keen on the player.
While Villa may be keen it looks like Charlton have got their man.
The report claims that a deal has been agreed between the two clubs and all that remains for it to be confirmed is a medical.
Bauer played 36 games for the club last season and will provide top quality reinforcements to their defensive positions for the 2015-16 campaign.
