The 25 year-old is thought to be a target for the club due to the return to Barcelona by on loan wide man Gerard Deulofeu and believe that the 8 million pound rated Ivan Perisic could replace the young Spanish player.
Perisic who impressed in Croatia's opening match against Brazil which unfortunately ended up in a loss for the European side could be hot property by the end of their campaign meaning that the Toffees would be wanting to close a deal early if they are indeed serious in their interest.
The former Dortmund player only joined Wolfsburg 18 months ago and despite scoring 10 goals and making 5 assists in the Bundesliga this season, the Volkswagen owned club would be prepared to cash in on their prized recruit to strengthen other areas of their team.
The midfielder can play both on the left and right sides of the wing while also being able to play as the second striker so would be a valuable addition to any side who is lacking in attacking depth.
