Rotterdam, Netherlands (My Sportsbook) - Ajax and Feyenoord clash Sunday as the top two teams in the Eredivisie for the first time in 13 years, adding a little more fire to an already heated rivalry.

Ajax is the lone unbeaten after 10 league matches, but Feyenoord has one more win, equal points and is second only on goal differential.

On the field is not the only concern for each side as a turbulent history has surrounded the rivalry for many years, most notably the death of two Ajax fans in 1997.

With a history of derogatory chants and other violence, both clubs have warned that banning visiting fans may be the only solution if problems continue.

All the clubs want to worry about Sunday is deciding which side will sit atop the league headed into an international break for EURO 2008 qualifiers.

Feyenoord (8-2-0) needs a victory to take over the top spot, but although it's a huge rivalry, manager Bert van Marwijk cautioned it's just one match.

"It's a special match of course, but on the other hand we can only get three points like every other week," he said. "If we then won all our games we'd be champions after all."

Feyenoord has relied on its defense this season, posting seven shutouts so far after allowing 66 goals in 34 games last season. The defense faces its biggest test against Ajax, which has scored a league-high 31 goals.

Ajax has been led by striker Klaas-Jan Huntelaar, who has 11 goals in 10 games this season. Luis Suarez has chipped in seven goals.

"Ajax is very strong in attack," van Marwijk said.

Roy Makaay leads Feyenoord with six goals.

Feyenoord could welcome back Andwele Slory, who has been out since the first match of the season, and Chun-Soo Lee and Kevin Hofland may also play larger roles.

Feyenoord has just one victory in its last five home games against Ajax, and just two wins in the last 10 games in the series.

Ajax has continued to play well under coach Ardie Koster, who was forced into the managing role when Henk ten Cate left to join Chelsea earlier this season.

Koster, who only joined the club in 2006, knows playing at Feyenoord is a big challenge.

"Feyenoord are a solid team, a good collective," Koster said. "At home they have not conceded a goal yet. But we always create opportunities. We have to prevent that Feyenoord lull us to sleep, after which their forwards strike.

"I am really looking forward to it."

On Friday, Jhonny van Beukering, Jeremain Lens and Muslu Nalbantoglu scored as NEC defeated Heracles, 3-0.

On Saturday, Twente hosts NAC, Graafschap hosts Excelsior, Venlo hosts Sparta and Willem II hosts Utrecht.

Also on Sunday, PSV hosts AZ, Vitesse hosts Heerenveen and Roda hosts Groningen.
