FANS were left gasping “I thought he retired” as legendary Sky Sports commentator Martin Tyler returned to UK screens.

The man known as the “Voice of the Premier League” left his role at Sky last year after 33 years in the beautiful game.

Tyler brought fans many memorable moments, including the famous Sergio Aguero line as Man City netted late goals to win their first Premier League title in 2011.

The ace’s absence was notable last term, with many lamenting his exit.

But contrary to belief, Tyler has not yet retired.

And he delighted fans by returning to screens for Sky rival TNT Sports.

Tyler delivered a passionate performance as he commentated on Atletico Madrid’s Champions League group stage defeat to Benfica.

And supporters quickly took to social media to express their surprise and delight.

One said: “I thought Martin Tyler had retired?”

Another declared: “Martin Tyler on TNT Sports, what on earth.”

One added: “When you sign up Tyler it seems odd to relegate him to a game nobody is watching.”

However, it’s not the first time Tyler has appeared on TNT Sports.

Around Christmas last year, he took over commentary duties for the group game between Porto and Shakhtar Donetsk.

Tyler also works with the Premier League’s production team.

And he provides commentary for the worldwide feed of English top-flight games.
