Coudet has replaced the sacked Oscar Garcia, arriving from Internacional.
On first impressions, Tapia says: "He wants a lot of intensity, he asks that we dare and be brave to play.
"We're very happy with the new coaching staff and I hope they bring us many triumphs."
Of his personal form, Tapia added: "I am very happy. I haven't had this continuity for a long time. I feel very good and I can show a lot more. I work for that."
