Hughes believes the signing of the Togo international was a major step forward for the club.
“Emmanuel has been one of the top forwards in the Premier League since he arrived from France and we are delighted he has agreed to come and join us,” he said.
“Along with the other signings we have made in the last two windows he will greatly enhance our ability to compete with the top sides.
“His arrival is another clear indication that we are determined to augment the players we have here with the best of international talent.
“He adds vital balance and power to our attack. He has everything a top forward needs. He is versatile, powerful, quick and agile on the ball.
“I am looking forward to working with him as are the rest of the staff. He will definitely add a new dimension to our play. I have been a great admirer for a long time.”
