Alex Albon says he is looking forward to a "more normal" 2020 season.
The British-born Thai rookie had a rollercoaster ride in 2019.
He began as a dumped Red Bull junior with a Formula E contract, then got an unexpected call-up to Toro Rosso, and finally replaced Pierre Gasly at the senior team.
"This year, for my first year, it definitely wasn't normal," Albon smiled.
"I'm feeling that next year will be a bit more normal."
Albon's task in the second half of the season was particularly difficult, as at the wheel of an unfamiliar top car the 23-year-old suddenly had Max Verstappen as his teammate.
"What better way to learn and to prepare myself than to have a teammate who's one of the fastest on the grid?" he said.
"He has had a lot of years within the team and knows how to extrapolate the best from it. For me, it's still a learning process.
"But it's a good thing and a goal to chase."
Albon says his task for 2020 is to finally "mix it at the front".
"The gap is shrinking and it's looking positive for next year," he said.
