The 24-year-old started his country's quarter-final defeat to Germany, but was replaced by Arsenal centre-back Laurent Koscielny after coming off injured in the second half.
France had enjoyed a promising tournament up until their clash with the Germans, but fell to a Mats Hummels header and failed to hit back with any attacking urgency.
However, Sakho posted a reflective message to his fans on Twitter the night after the match.
Dur de trouver les mots, notre déception est immense ce soir ! Mais nous n'avons pas tout perdu...— Mamadou Sakho (@mamadousakho3) July 4, 2014
Mais nous n'avons pas tout perdu. Nous avons gagné le soutien de tout un peuple et ça, ça n'a pas de prix ! MERCI !!! pic.twitter.com/lfpCH3zzrv— Mamadou Sakho (@mamadousakho3) July 4, 2014
The message reads: 'Hard to find the words, our disappointment is huge tonight! But we will not have lost everything...
'We won the support of a whole people and that has no price! Thank you!'
Sakho's comments may be alluding to the fact that the French public were less than enamoured with the national side after the last World Cup in South Africa, when Les Bleus returned home disgraced after talk of rebellion and player strikes.
This year's tournament has gone smoother in every way and - bar one lifeless display - has brought genuine hope to the nation.
Sakho's next footballing duties will be to return to Anfield, where Liverpool will participate in the Champions League once again, as well as look to challenge on all domestic fronts.
The 24-year-old made four appearances for France at the World Cup on the back of a gruelling Premier League season, where Sakho's club side finished just two points short of champions Manchester City.
