The 31-year-old, who spent four years on Tyneside after a club record £16 million move from Real Madrid, received a hostile welcome from Newcastle fans as he was introduced as an 80th-minute replacement for Nani during Tuesday's 0-0 draw.
Responding via his Twitter account, Owen said: Got a poor reception off the home fans which was disappointing.
Was desperate to score!
He added: Knew I would get booed as that's what a lot of fans do, but if they knew the facts, then they may have a different opinion.
Owen, who earned £103,000 a week during his injuryplagued time with the Magpies, left in the wake of the club's relegation to the Championship at the end of the 2008- 09 campaign.
He defended himself amid further criticism in a series of later posts.
The striker said: From what most of you are saying, you should be pleased I left the club! If I had known that earlier I could have left sooner!
For the record, I tried my best in every game for Newcastle.
Under KK (Kevin Keegan), I played well and I'll never forget the 2 I scored against Sunderland.
When I meet Newcastle or Liverpool fans, they all respect what I've done for their clubs.
In stadiums it changes, 1 boo and the rest follow.
By the way, I'm not looking for sympathy. As long as my family don't boo me when I walk through the door, I couldn't care less!!!
