Marc-Antoine Fortune claims he did not need to hear Tony Mowbray give a public vote of confidence in his abilities.
The former Nancy striker was left out of the Active Nation Scottish Cup fifth-round win over Dunfermline last Sunday as new signings Robbie Keane, Morten Rasmussen and Diomansy Kamara all got on the scoresheet in the 4-2 win.
Fortune, now with nine goals under his belt ahead of the trip to Aberdeen on Saturday, said: "My confidence has always been the same.
"People told me what the manager had said in the media about me but my confidence was already high so that is just a bonus.
"He came here to build a strong team for Celtic and he will keep going the same way.
"It is a new team, there are some guys away, some have arrived, so it is different.
"There are a lot of new players but with work we can get better and better."
