The Football Association have confirmed they are to study a video of an incident between Neil Warnock and Stephane Henchoz at the end of Liverpool's Worthington Cup semi-final win over Sheffield United.
Warnock was furious following the match, which Liverpool won 2-0 after extra time to progress on aggregate, and claimed the Swiss defender spat at him.
Liverpool coach Sammy Lee had to restrain the United manager, although Henchoz and Liverpool manager Gerard Houllier have dismissed Warnock's accusations.
The FA will now study a video of the incident to determine whether either man has a case to answer.
