West Ham United face competition from Arsenal and Barcelona over the signature of Juventus striker Mario Mandzukic, according to reports.
The 30-year-old played under Hammers boss Slaven Bilic for the Croatian national team and is likely to find first-team opportunities in Turin limited this season following the arrival of Gonzalo Higuain from Napoli.
According to Mundo Deportivo, the Blaugrana are looking into Mandzukic as a back-up to their famed attacking trio of Lionel Messi, Luis Suarez and Neymar, while the Gunners are also said to be in the market for a striker.
Mandzukic joined the Serie A champions last summer in a £16.1m deal from Atletico Madrid and scored 13 goals in 36 appearances.
