Swansea City Boss Bob Bradley says they need to replace former striker Andre Ayew and ex-captain Ashley William.
Andre Ayew scored 12 Premier League goals for Swansea but was sold to West Ham after just one season at the club.
Defender Williams played more than 300 times for the Swans after joining from Stockport County in 2008 but moved to Everton during the summer.
“All Swansea supporters know that they were important players last year,” Bradley told BBC Radio 5 live.
“When players like that leave, not only do you lose the talent they had on the field, but both of those players were strong figures in the dressing room.”
The Swans are 19th in the Premier League, only a point ahead of Sunderland.
