WORLD drivers' champion Ayrton Senna and young German challenger

Michael Schumacher almost came to blows after a clash during the second

day's testing for next week's German Grand Prix in Hockenheim, where

Nigel Mansell clocked the fastest lap in his Williams.

Senna accused Schumacher, with whom he has clashed twice already this

year, of endangering him by blocking his line.
