The France international was introduced as a late substitute as we beat the Toffees by the odd goal in five to keep up our winning momentum in the Premier League.
With attentions now turning back to the world-renowned cup competition and another tricky tie with lower-league opposition on Sunday, Moussa believes another intense display will be required in order to avoid an upset.
“Nobody will gift you the chance to win the game so we have to play our football, stay focused and play this game like we played last Sunday against Everton if we want to go to the next round,” said the 27-year-old.
