Congo Brazzaville coach Sebastien Migne praised the Egyptian national team before the clash between the two teams in the fifth round of the 2018 FIFA World Cup qualifiers.
Egypt has become the second African country to qualify for the 2018 FIFA World Cup in Russian Federation after defeating Congo at Borg El Arab Stadium.
A scoreless first half raised the nerves in Alexandria but Salah's first of the night put one Egyptian foot in Russian Federation.
After a 0-0 first half, Salah eventually calmed the Egyptian fans nerves by breaking the deadlock in the 63rd minute.
Egypt have won four Africa Cup of Nations titles since 1990 - in 1998, 2006, 2008 and 2010 - but fallen consistently short in World Cup qualification.
But Congo threatened to turn party-poopers as substitute Moutou, a France-based defender, beat 44-year-old goalkeeper Essam El Hadary from inside the box.
However, the Pharaohs were awarded a penalty in the fifth minute of stoppage time.
They had suffered repeated heart-break instead, with one of the most painful defeats coming in 2009 when losing a bitterly-contested play-off against Algeria.
But a late penalty from Salah ensured Egypt will be in Russian Federation, making them the second African nation to qualify after Nigeria's nervy win on Saturday against Zambia.
Egypt haven't reached the World Cup finals since 1990, and they were in need for a victory in Alexandria to guarantee their ticket to Russian Federation.
"It's been 28 years and we're finally going to enter the World Cup".
