The 29-year-old Irishman struggled to produce his best form for the Toffees last season, but started for his country in the flat draw against England yesterday.
Collymore has suggested that having watched him closely last season, he sees some real potential which Everton boss Roberto Martinez can use to his advantage.
“I’m surprised (at the criticism) because every time I’ve watched him, which has been maybe four or five times, he’s played well and has showcased his talent,” said Collymore.
The issue for Martinez is unlikely to be one related to whether the player is good enough, but one where there is a question over his consistency.
It was difficult for him in the last campaign because he started ten games and came off the bench for six (in the Premier League) which means his role was always changing.
It’s difficult for any player to get his head down and produce his best form when there is uncertainty over whether he’ll be starting or whether he’s seen as more of an impact player to come off of the bench.
Martinez has to define him and give him a clear idea over his role under his guidance, which can then allow him to accept that and focus on it or potentially consider whether Everton is the best place for him to be playing his football.
