The former Liverpool and Real Madrid frontman was an unused substitute during Capello's first match in charge - a 2-1 win over Switzerland on 6 February.
"The new manager has only had one game in charge and that was a friendly so we will see what develops," added Owen.
The Magpies are three points above the drop zone in 15th place and face crucial matches against fellow-strugglers Birmingham, Fulham and Reading in three of their next four matches.
Owen added: "We are expected to get points and we need to pick them up now.
"There are certain clubs that criticism attracts. People see the support we get and if we are not up there in the prominent positions then people ask why.
"But I'm at a club where you feel like a spark will get us back on the crest of the wave and help us move up the league - that can give us a platform to build on."
