The Belgium international missed the club's entire pre-season preparations with a back injury and has yet to feature this term.
The 27-year-old has returned to training though and is using the international break to try and build up his fitness.
He admits Arsenal's Premier League clash at Sunderland on September 14 is too soon for a return, but the League Cup trip to the Baggies on September 25 could see him finally pull a Gunners shirt on again.
"The West Brom game is a few weeks away yet and hopefully I will be closer to a return myself in the meantime," the former Ajax stopper told reporters.
"West Brom looks like an interesting draw - it looks like a tough game but a nice game too. It's one we will take seriously and with a high focus.
"I can't put a date on my comeback yet, as it depends on how I respond to the physical work I am doing, but I am focusing day by day and am really happy with how things are going so far."
