Schalke manager Felix Magath is refusing to get drawn into mind games with Bayern Munich ahead of their crucial Bundesliga clash in Gelsenkirchen this weekend.
His side lead Louis Van Gaal's men by two points and a win would see them move five clear with five games to go, but a Bayern success would make for an exciting climax to the campaign.
However, the Bavarian outfit have lodged a complaint to the German Football League (DFL) over the state of the Arena AufSchalke pitch and it has added to the tension ahead of the showdown.
"We would be well advised to concentrate completely on the sporting aspects," Magath said.
"There are more important things for me. My team will provide the answer on the field."
