The midfielder has served notice he is poised to cause a stir in the Italian top flight after spending some time in the Serie B last season to psyche himself up
The 20-year-old midfielder spent last season on loan at Serie B side Sassuolo from Genoa.
He played in almost all the matches of Sassuolo and helped them to reach the promotion play offs.
Chievo Verona share a 50-50 ownership right of the player with Genoa in the four-year deal.
In an interview with Goal.com Ghana, Cofie said: “I am happy to be back in the Serie A after a brief stint with Genoa before I was loaned out to clubs in the Serie B.”
“I have learnt a lot from my Serie B campaign and I know I will make an impact in the Italian top flight because I want to play for the national team, the Black Stars,” the midfielder added.
The Gialloblu finished 10th in the 2011-2012 season and believe the Ghanaian can help them in their campaign come the new season.
Cofie who has also been on loan at Torino and Piacenza was invited by Ghana’s Under-23 team last year in the qualifiers for the 2011 All Africa games in Maputo, Mozambique.
