Manchester United have joined the interest for Napoli star Ezequiel Lavezzi.

Gazzetta dello Sport says United had scouts in the stands to see Lavezzi score in victory over Udinese this week.

The Argentina international can add the 'fantasy' United badly missed in Sunday's humiliation against Manchester City.

For their part, City are also keen on Lavezzi, which has been confirmed by manager Roberto Mancini and his scout Faustino Salsano in recent weeks.
