Half time scoreline a totally accurate reflection of the gulf between the two sides.
Impressed with Algeria in that half and impressed with them in this World Cup in general; they're composed in possession, they get into good areas going forward and create good chances - it's just the finishing which lets them down and was partially to blame for the Belgium defeat.
Also, unlike the majority of the African teams, they actually try and attack throughout the game rather than playing mostly in their defensive third and trying to catch their opponents out on the counter.
On that basis - and providing they play sensibly against Russia and don't go too gung-ho - I fully expect them to go through with Belgium.
Interestingly, if they do get through the group as runners up, the likelihood is they'd have a second round tie against Germany - which would be a repeat of the famous match in 1982 which Algeria won 2-1.
