Sunderland midfielder Sebastian Larsson is braced for an Arsenal return this weekend.
The Swedish international endured a tough spell with the Gunners before leaving for Birmingham City, originally on loan, and then Sunderland four years later in the summer.
Linked with a surprise return to the Emirates in the transfer window, Larsson has settled into life with the Black Cats well, and is hoping to inflict further punishment on old boss Arsene Wenger this weekend.
"For this one game I'll be more than happy to make that happen and see Arsenal struggle," said the 26-year-old.
"The fear factor has gone a little but if they do put in a good performance then you will be in for a hell of a tough day.
"Since my time there I have always followed Arsenal. I am just worried about what we are doing though, we need to start picking up points."
Both clubs are struggling at the lower end of the table, with Arsenal sitting 15th in the Barclays Premier League after their worst start to season in over 50 years.
A victory on Sunday could be the start of a resurgence for Wenger, who is hoping his summer signings can gel quickly to help propel Arsenal back up the table.
