"Robin is passionate about the game," said Wenger.
"He was a little bit sidelined in Holland when we bought him and [during the] first year we observed him when he was more on the bench. In fact, we watched him more in the reserves than in the first team.
"When he arrived here it was a big move for him physically and mentally, however I believe he has survived because of his talent and his intelligence but mainly because of his passion for the game.
"Robin wanted absolutely to make it. He has developed less on his individual talent than as a team player."
