Former Celtic striker Jan Vennegoor of Hesselink believes Neil Lennon has an amazing appetite for winning.
The current Hoops boss is on the verge of securing a second Scottish Premier League title, as well as preparing for the Scottish Cup semi-0final this weekend, and the Dutchman says he is unlikely to want to stop there.
"If you look how he (Lennon) did in the Champions League and in the league, he is doing his job really well," the former Holland international said.
"Sometimes you have slip-ups but they are 15 points clear so that says enough.
"I know Lenny a little bit and he will want to win the cup and get the double. As a footballer, there is a competitiveness, you want to win.
"It is like an addiction and if you win prizes you want to do it over and over.
"I think that is in the mind of Lenny and hopefully in the minds of a lot of players."
