The Australian midfielder scored the only goal in Everton’s 1-0 win over Wigan Athletic at the DW Stadium, his second for the week after netting early in the 2-0 win over Sunderland midweek, and Moyes was full of praise for the match winner.
''It was trademark Tim Cahill,'' Moyes said. ''He knows he is capable of that, and he has probably not shown it quite as much this year.
''I think he is looking fitter and he has played better in the last six weeks and he is starting to feel much more like himself.
''Tim Cahill has always come up with important goals for us, and he's done it again today.''
Cahill, who started the season slowly but has found form in recent weeks, said that the win over Wigan was important as it gave the team plenty of momentum going into the Merseyside derby with Liverpool next weekend.
''The belief and confidence has always been there,'' Cahill said. ''The three points was vital for us to keep our momentum.''
