The Round 9 menu presents predictors with some of the toughest decisions of the season thus far. In our first look at the Round 9 fixture list, we turn our attention to the action in Scotland, Spain, Japan, Germany and Mexico.

Match of the week: The Old Firm Derby
Celtic-Rangers (Scotland)

Derbies don’t come much more bigger or more passionate than Glasgow’s Old Firm, a rivalry that has been running since 1888 and once pulled in an attendance of 132,870 (in the 1969 Scottish Cup Final). This year, the Glasgow giants are locked at the top of the Scottish league table on 24 points apiece and are the only remaining undefeated teams in the 2010/11 Scottish season. This impressive pre-derby form has merely fuelled the excitment and anticipation for Sunday's match.

Spanish revival
Valencia-Mallorca (Spain)
Valencia suffered their first defeat of the season last weekend, when reigning La Liga champions' Barcelona came back from 1-0 down to snatch a 2-1 win. The result knocked Valencia from the summit and Los Che will look to quickly bounce back when they host mid-table Mallorca on Saturday. The odds appear to be against Mallorca coming away with any points, but back the underdogs and you could claim almost 100 points.

Stakes high in Japan
Vissel Kobe-Nagoya Grampus Eight (Japan)
With only eight games left in the current J-League season, the pressure appears to be taking its toll on some of the frontrunners. This past weekend, Nagoya Grampus crashed 4-1 to midtable Albirex Niigata. Next up for the league leaders is a trip to Vissel Kobe. The relegation-threatened hosts lost 2-0 in their last encounter with Grampus in Toyota City but recent results have shown that the struggling side are stronger at home than on the road. Vissel Kobe enter the match undefeated in their last four home games, although they have only scored once in those four outings.

Eintracht Frankfurt-Schalke 04 (Germany)
Frankfurt have come out losers on their five most recent league meetings with Schalke 04. The last time these two teams met was back in March 2010, with Schalke running rampant in a 4-1 win in Frankfurt. Looking at the pair’s head-to-head record -  27 wins for Eintracht Frankfurt, 29 for Schalke 04 and 18 draws - it could hardly be any tighter ahead of Saturday's meeting.

Santos Laguna - Monterrey (Mexico)
Off the back of a 3-0 loss to league leaders Cruz Azul, Santos Laguna next face second-placed Monterrey, the only undefeated team in the 2010/11 Mexican Apertura. The match will also be a meeting of the current two top scorers in Mexico. Christian Benitez leads the pack on 11 goals, with Monterrey’s Humberto Suazo follows close behind in second place on 9 goals.
