Arteta appreciated Rice's quick learning and positive response to constructive criticism and at the same time hailed his humility and intelligence in handling the pressure following a big-money move from the Hammers.
"When they put the price tag, you have to carry that and it is not easy. He has done it in a brilliant way,” Arteta said.
“He is really humble and the way he takes positive criticism is really powerful. Every time you switch the TV on, they will be talking about Arsenal and talking about Declan.
“There were a lot of question marks and that’s something you have to overcome because they’re going to be looking at every statistic and every movement that you make. Then take things in a way that is constructive and put it in the context of ‘in game to game, action to action’ — this can change very quickly. He’s very intelligent to manage it.”
Rice will be in action against his former employers, West Ham, on Thursday at the Emirates.
