The former QPR midfielder has left League One Pompey to link up with the Championship club until the end of the year and is looking forward to pushing his way back towards Premier League football.
"I'm optimistic, I'm ready to fight. I could get into good form at Portsmouth during one and a half months, I could play seven games," he said.
"I got this chance and by this move, I'm one step close to the (Premier League) stage I want to get back to.
"I'll be here on loan until the end of December and Barnsley will have eight games during this period so I'll have time to prove that I can produce well on this stage."
