Everton have reportedly been tracking Ivan Perisic as they search for a replacement for Gerard Deulofeu.
The Barcelona midfielder has returned to his parent club after spending last season on loan at Goodison Park.
The Express reports that Roberto Martinez has highlighted the Wolfsburg winger as a potential replacement, and that the club have made an £8m bid for the Croatia international.
Italian clubs Juventus, Napoli and Roma have also been linked with Perisic this summer.
