Emmanuel Eboue is confident Arsenal's shock defeat to West Bromwich Albion is now forgotten.
Eboue feels Tuesday's 3-1 UEFA Champions League triumph at Partizan Belgrade has put his side back on course as they prepare to visit Chelsea at the weekend.
"We started very well in the league, but last Saturday's defeat was a big blow," Eboue told skysports.com.
"But our spirit is strong, we came away from home in Europe and won 3-1.
"Our winning mentality is back, and we really need that to meet Chelsea on Sunday."
