Atletico Madrid are moving for Lille defender Zeki Celik.
Atletico see Celik as a replacement for Kieran Trippier, who has been sold to Newcastle United.
Atletico coach Diego Simeone had favoured a move for Chelsea defender Cesar Azpilicueta. But with Chelsea reluctant to do business, Atletico are now turning to Celik.
Lille are prepared to sell Celik for around €15-20m.
Atletico are determined to find Simeone a replacement for Trippier, with the coach disappointed to lose the England international.
