Liverpool target Marc Guehi appeared to snub Crystal Palace manager Oliver Glasner moments after the full-time whistle of his side's goalless draw with Chelsea - fuelling another famous rant by Roy Keane.
Sky Sports cameras showed Glasner shouting over to Guehi only for the England centre back to head straight towards the tunnel, leaving Glasner visibly confused.
The alleged snub led to Keane hitting out at a new fad in football which sees managers take to the pitch to speak to their players once the referee blows for full-time.
