Nottingham Forest test waters for Bologna striker Santiago Castro

Nottingham Forest have reportedly stepped up their interest in Bologna striker Santiago Castro after making initial enquiries about a potential summer transfer.

The Argentine forward has emerged as one of Serie A's most promising young attackers since arriving in Italy, and his performances have begun attracting increasing attention from Premier League clubs.

According to reports in Italy, Forest have already "tested the waters" for the 21-year-old, although no formal offer has yet been submitted.

Italian outlet Quotidiano Sportivo reports that Forest have made preliminary checks on Castro's situation as they assess attacking reinforcements ahead of the new season.

The report claims the Premier League side remain interested following previous scouting missions and have now begun gathering information regarding the conditions of a possible transfer.

One factor that could work in Forest's favour is their strong relationship with Bologna.

The two clubs have conducted several successful deals in recent years, including the moves involving Nicolas Dominguez and Remo Freuler. Forest also secured the signing of Dan Ndoye from Bologna last summer, creating a positive working relationship between the clubs.

That history may help if negotiations eventually progress beyond the exploratory stage.

Forest are not alone in their admiration.

Both Aston Villa and Chelsea are reported to have monitored Castro closely, and wider interest could increase if Bologna actively place him on the market.

For Forest, the appeal is obvious.

At 21, Castro combines youth with meaningful first-team experience, while his potential ceiling remains high. He would also fit the club's recent strategy of recruiting young players capable of developing further in the Premier League.

Forest have only made initial enquiries and significant work would still be required before any agreement could be reached.

Forest are expected to continue monitoring Castro's situation while assessing other attacking targets. Bologna's willingness to sell could become clearer as the summer window progresses and financial decisions are made.

If the Italian club actively seek a major sale, competition from Aston Villa, Chelsea and potentially other Premier League sides could intensify. Much will depend on Bologna's asking price and whether interested clubs view Castro as ready to make the next step.

For now, Nottingham Forest have established their interest, but the race for one of Serie A's most promising young forwards appears only to be beginning.

Would Santiago Castro be worth a €40m-plus investment for Nottingham Forest, or should the Argentine striker spend another season developing at Bologna?
