MILAN (Reuters) - Italian private broadcaster Mediaset MS.MI is not interested in buying the TV broadcasting rights for the next three seasons of Serie A matches from Spain's Mediapro, following its deal with Sky SKYB.L, a source said on Tuesday.

On Friday the Milan-based TV group signed an agreement to air its pay-TV Cinema and TV series channels on Sky Italia’s satellite while Sky will be able to offer customers its own services on Mediaset’s digital platform.

In February, Spanish broker Mediapro bought the rights to broadcast top flight Serie A soccer matches for 2018-2021 at 1.05 billion euros per season and must sell the rights to other entities.

The group was expected to start talks with both Mediaset and Sky in coming days for the sale.

Mediaset was not immediately available for comment.
