They’re looking for a repeat come March at this season’s Aviva Premiership Derby Day fixture, in front of 57 thousand fans.
“As a visionary and innovative club we are delighted to be teaming up with a stadium and team that matches our ambition to create a landmark showpiece event,” Saracens’ Oren Bowman says.
“London Stadium has become synonymous with delivering great entertainment and sporting spectacles and this opportunity is one that both parties are very excited about.”
