The Lupi progressed to the Quarter-Finals after eliminating Ukrainian club Shakhtar Donetsk in the Round of 16, and after drawing the Dutch giants on Friday, the 48-year-old lavished praise on their style of football.
“Ajax are a very strong team, one of the best in the Europa League,” Fonseca told Sky Sport Italia.
“They have a beautiful European project, we expect a very difficult tie. There is the most consolidated football school in Europe but we have our chances.
“Now we must study them well. I think that we will have a balanced encounter. We are very motivated to face Ajax.
“With Shakhtar, we played two great matches and they were a difficult opponent. The team played well and with confidence.”
Should the Giallorossi eliminate Ajax, they will face one of Manchester United or Granada in the Semi-Finals.
