Arsenal boss Arsene Wenger was delighted with two-goal Tomas Rosicky after victory at West Bromwich Albion.
Rosicky struck in both halves of Arsenal's 2-1 win in what was only his second league start of the campaign.
Wenger said: "Tomas was fantastic. He is an important player for us. Unfortunately he was out injured for a long time.
"But every year he gives us a push at the end of the season. I hope he finishes his career with us. I rate him that highly."
