It was Lichtsteiner who initially lost possession in midfield, allowing Messi the opportunity to set up the Real Madrid winger, and the 30-year-old admits that he played a role in Switzerland's downfall.
"Switzerland deserve praise for a great performance and we didn't deserve to go out like that," he told Sky Sport Italia.
"We proved that we are a very good side and it was a wonderful game for us until that moment.
"On the goal I lost the ball after a challenge and they were able to run in on goal. We were punished when the match was practically over. It's such a shame."
