Who are the players most continuously loyal to their clubs across the planet?

Valentine's Day is an opportunity for many to show their commitment to their loved ones - but not all footballers have the same loyalty to one club.

The modern game sees many players move away from their boyhood clubs and the locations of their youth experience to get more game time, or to move through the ranks towards the upper reaches of football.

So it can be a surprise to discover the players who have the longest unbroken spell with their clubs in the top leagues across the world - with some staying in one place for more than 20 years.

The CIES Football Observatory has highlighted footballers from 60 leagues across the planet who have the longest unbroken spell representing the same club.

Russian goalkeeper Igor Akinfeev has been at CSKA Moscow for 21 years, a feat which is almost unparalleled in the modern game.

In joint second place globally, Akhmat Grozny defender Rizvan Utsiev and Al-Jazira Club goalkeeper Ali Khaseif have both spent 19 years representing their respective clubs.

Just below those are five players who have spent 18 years with the same club, including 36-year-old defender Lewis Stevenson who has spent half his life on the books at Scottish club Hibernian.

In the big five European leagues, there are only 11 players who have spent 13 years at one club - and two Germans top the table.

Thomas Muller at Bayern Munich and Tony Jantschke at Borussia Monchengladbach are currently playing their sixteenth consecutive season with their respective clubs.

The rest of the top five is made up of Spanish players, with Athletic Club’s Iker Muniain and Oscar de Marcos, as well as Atletico Madrid’s Koke Resurreccion all with 15 years of service to their teams.

Everton's Seamus Coleman was the only player in the Premier League to make the top ten list, for the defender's 14 years with the Toffees.

Crystal Palace defender Joel Ward, Borussia Dortmund's Marco Reus and Real Madrid's Luka Modric are among those who fall just short of the top 10, with 12 years of continuous service to their respective teams.
