Gudjohnsen has travelled across Europe in a successful career for the 37-year-old, and is currently preparing for a last-16 clash with England at Euro 2016.
The Iceland international, formerly of Chelsea, Barcelona, Monaco and Tottenham Hotspur tweeted earlier this week to claim his country’s final group-stage match against Austria was the biggest game of his career.

The veteran striker played no part as his side, making their debut in a European Championship finals, set up a knockout-round meeting with the Three Lions with a 2-1 victory.
And with Monday’s clash ticking ever close Gudjohnsen has reflected on his time in English football, which he says easily beats the three years he spent at Barcelona despite winning the Champions League, La Liga and Copa del Rey at the Nou Camp.
“It’s fair to say, there’s two clubs in England have been more to me than just football clubs. It’s Bolton Wanderers and Chelsea,” he said, as quoted by the Mirror.
“They are not just ex-clubs, they are clubs that I have feelings for, love for because of my time there.
“Of course Chelsea had little bit extra, it was my first taste of success, it was a time that I cherish. Chelsea will always be my number one club in football.
“I had a lovely experience in Barcelona, but the role I played in Chelsea and the success that I had there was probably the best time in my career and the most enjoyable so far.”
Gudjohnsen spent a number of years on English shores, where he also turned out for Stoke City and Fulham before leaving his second stint at Bolton Wanderers in 2015.
In total, he scored 55 goals in 211 appearances in the Premier League, which he won in back-to-back seasons at Stamford Bridge.
At 37, he has played only 12 minutes of action at Euro 2016 so far but will be hoping to strike a telling blow on Monday night when Iceland face England at the Stade de Nice.
