The Portugal midfielder failed to inspire his team-mates as goals from Stones and Fernandinho consigned the hosts to defeat
Manchester United star Bruno Fernandes found himself in Roy Keane's firing line after going down to a 2-0 defeat to Manchester City on Wednesday.
The Reds' Carabao Cup hopes were extinguished at the semi-final stage as the holders proved too strong at Old Trafford.
John Stones gave the visitors the lead five minutes after the half-time restart, before Fernandinho put the result beyond doubt in the final stages to keep Pep Guardiola's men on track for a fourth straight success in the competition.
