Huracan midfielder Mario Bolatti is a surprise target for Barcelona.

Ole says Barca sports director Txiki Begiristain has already opened talks with Bolatti's representatives about a price for the midfielder.

The midfielder's registration is a complicated matter, however, with Huracan holding 20 per cent, Porto 40 per cent and the remaining 40 per cent owned by a group of investors.

Sevilla are also monitoring the situation.
