The production nevertheless remained striking. In 2018–19 he scored 19 goals and supplied 13 assists in 28 appearances, earning a second successive leading assist-provider distinction.

Availability then declined: 23 appearances in 2020–21 and 18 in 2021–22, with 15 goals and eight assists in the former and 13 goals and eight assists in the latter.
