Cottee has lent his backing to the 26-year-old to carry the predatory instincts which saw him take League One by storm into the Premier League.
"Of course it's a gamble when you sign any player from a lower division whether it's Championship or League One in this case" said Cottee.
"But what I would do is point to David Moyes, who is fantastic manager, as someone who has already done well with players like Tim Cahill and Phil Jagielka.
"There is a real pool of talent in the lower leagues and in my work for Sky I go all round the country and I see a lot of good players who are not given the chance, so I think it is fantastic that David and Everton are doing what other clubs are not; others will go and get a free signing from Norway for example because it's the cheap option. Jermaine has cost a little bit of money in terms of his wages but it is great Everton are willing to take a chance on him."
