Championship side Fulham have signed Denis Odoi from Belgian club Lokeren for an undisclosed fee, while Tomas Kalas has joined on loan from Chelsea.
Full-back Odoi, 28, has agreed a three-year contract at Craven Cottage, with the option of a further year.
Blues centre-back Kalas has joined on a season-long loan deal.
The 23-year-old Czech Republic international has spent the last 18 months on loan at Middlesbrough, making 47 appearances.
Kalas joined the Blues in 2010 and has featured four times for the Premier League club, while also having loan spells at Sigma Olomouc in his homeland, at Dutch side Vitesse Arnhem and with German outfit Cologne.
The pair become Fulham’s fourth and fifth signings of the summer transfer window.
