Barca could yet splash out on a midfield addition before Friday's transfer deadline, says Sport.
And while Ajax whiz Frenkie de Jong is the priority, Kampl is also under consideration as an alternative.
Barca coach Ernesto Valverde is concerned about his midfield options, particularly if Rafinha is allowed to leave in the coming days. As such, he has requested a midfield signing be made.
De Jong is the player Barca want, but Ajax chief Marc Overmars is proving a stubborn negotiator - which has led to an enquiry being lodged with RBL for Kampl this past weekend.
