Barcelona are watching Ajax midfielder Frenkie de Jong this season.
El Mundo Deportivo says Barca see De Jong as cover and as an eventual successor for Sergio Busquets.
The young Dutchman, 20, has been watched regularly by Barca this season and could attract an offer this summer - if pushed.
The Catalans would prefer to wait until 2019 before moving for De Jong, but plans could be brought forward if rivals emerge in the coming months.
Along with De Jong, Barca are also watching his Ajax teammates Matthijs de Ligt and Justin Kluivert.
