Barcelona will insist on a buy-back option if they're to part with Carles Alena.
The midfielder is a target for Tottenham, where he is seen as a potential replacement for Christian Eriksen.
Mundo Deportivo says Barca are reluctant to cut all ties with Alena - and would prefer a loan arrangement.
However, if Spurs insist on a sale, then Barca will insist on a buy-back option.
For his part, the midfielder is keen to move after being frozen out this season.
