Fulham announced on Wednesday that Athletic Bilbao defender Fernando Amorebieta and Dnipro Dnipropetrovsk midfielder Derek Boateng have both joined the club on free transfers.
Venezuelan defender Amorebieta spent eight years at Bilbao and has signed a four-year contract with Fulham, while Ghana international Boateng arrives from Ukrainian club Dnipro on an initial one-year deal.
Fulham have now added three players to their squad for next season, having already taken up an option to turn Sascha Riether's loan move from Cologne into a permanent transfer.
The arrival of Amorebieta represents something of a coup, with Fulham having reportedly seen off interest in the 28-year-old from Arsenal, Everton and Russian heavyweights Zenit Saint Petersburg.
"I'm delighted to have signed a four-year deal with Fulham and I'm looking forward to competing in the Premier League next season," Amorebieta told the Fulham website.
"I'm impressed with the talent already at the club and I look forward to meeting the players for pre-season training in July."
