Nottingham Forest are "keen to keep hold" of Keylor Navas and Renan Lodi in the summer transfer window.
The duo have been on loan at Forest this season from Paris Saint-Germain and Atletico Madrid respectively, and have been crucial in recent weeks and months as the Reds secured their Premier League status.
Lodi joined on a season-long loan last summer, while Navas arrived in January after Dean Henderson picked up an injury that brought his campaign to an abrupt close.
