“He is a proper player who leads by example. That is the type of player you need in your football club.
“When you make a statement about a new manager coming in and buying new players, that's the type of player you buy. Declan Rice all day.”
Rice has been a key part of the Gunners' title challenge so far this year, missing just two of their 16 Premier League games.
In 20 appearances in all competitions, the 25-year-old scored one goal and added four assists from midfield.
The England international moved to the Emirates Stadium last summer for a club record £105million.

The three-time Premier League champion added: “I don't think it's imperative for United to move Viktor Gyokeres at the moment when you have Rasmus Hojlund.
“I think there are other areas I would prefer to focus on. I think the club needs a left-back. Luke Shaw is struggling with his injuries. He seems to suffer one after another, and you can't put your hopes on someone like that.
“Another really good midfielder would be fantastic, so I think there are other players and other areas to strengthen that are more important for him than buying another center forward. Hojlund is proving enough.”
Gyokeres signed for Sporting in 2023 for amorimscoring 66 goals in 68 appearances under his former boss.
Hojlund, for his part, has scored seven goals so far this season, five of them since Amorim's arrival.
