Lewis Hamilton feels that seeing McLaren struggle through the 2015 season is particularly difficult for him to watch.
Hamilton, who made his Formula 1 debut for the Woking-based outfit in 2007, drove in 110 races before he left at the end of 2012. In 2008 he won the world Drivers' Championship in the McLaren MP4-23.
The Briton has some sympathy for his old employers.
"We all know it's been difficult for them this year and it's definitely hard for me to see that," he told Autosport.
"It's such a great team, such a huge team, that's had such great success, and it's a team that I was a part of for many years.
"It feels very abnormal to see them in the position they're in right now."
McLaren have not won a grand prix since Hamilton’s departure. Fernando Alonso and Jenson Button, both former world champions, have only managed to score five points in the nine races so far this season.
Many of the team’s current struggles are due to a severely underperforming Honda engine, said to be 35km/h slower on the straights than their competitors.
Hamilton, however, believes that they can turn all their miserable form around and build for 2016, partly due to the massive levels of experience found at McLaren.
"You've got the great Ron Dennis there, a lot of great engineers, and a team spirit which eventually I believe will pull through," he said.
"It's a dark place for them right now but hopefully there is light at the end of the tunnel."
