Charlton boss Iain Dowie completed a £4million double swoop for Djimi Traore and Amdy Faye - and insisted his spending was not yet over.
Versatile defender Traore has joined from Liverpool and Faye arrives from Newcastle, each player costing Charlton £2million and each signing three-year contracts.
According to Charlton, Traore was also a target for Newcastle and Everton.
'We're delighted to have made two quality signings, and they will both improve our first-team squad,' said Dowie on the Charlton website.
'We're also working very hard on several other signings and we hope to be able to make further announcements soon.'
Charlton are finalising their preparations for the first season under Dowie, who replaced Alan Curbishley this summer.
The new boss has stated his intention to make either three or four new signings before Friday's friendly against Utrecht, suggesting one or two deals remain in the pipeline.
Traore will add strength predominantly on the left side of Charlton's defence, following the departure of veteran Chris Powell, however the 26-year-old is capable of playing in the centre too.
He spent seven seasons at Anfield, having joined in a £500,000 deal from Laval, and despite being often criticised as a weak link, Traore was a member of Liverpool's Champions League winning team in 2005.
Tough-tackling midfielder Faye spent 19 months at Newcastle, whom he joined from Portsmouth, but he was set to be squeezed out of manager Glenn Roeder's plans for the coming season due to the number of midfielders at St James' Park.
Roeder was content to see the 29-year-old leave, even if it meant him joining a rival Premiership club.
'He hasn't given me any problems whatsoever, but I just felt that with the midfielders we have at the club, it was best not to stand in his way with him being offered the chance of more regular football,' Roeder told club website.
'He was at our game with Villarreal at the weekend, and before he went down to London I wished him all the best for when the transfer went through.
'I hope he enjoys a good career at Charlton, though obviously not in the two games against us in the new season!'
