The 22-year-old Ghanaian has admitted Ajax would be very tough to overtake on the league log.
Ghana winger Christian Atsu has conceded his side Vitesse are not strong favourites for the 2013-14 Dutch Eredivisie title.
With seven matches to end the season, Ajax, who have a game in hand lead the log with 59 points, seven ahead of fourth-placed Vitesse.
Atsu said their main aim is to finish in a good position since toppling Ajax remain an uphill task.
“I think it will be very difficult to win the title. Ajax are a good team and it is difficult to see them lose.
“We are in the 4th position, and we will work hard to finish in a good position,” the former Porto player told Goal Ghana.
“The Dutch league is a very good competition, and the best place for young players because they like using young players here,” he added.
Atsu is currently on loan at Vitesse from English side Chelsea.
