Most teams played with wingers before when we played this formation.
It didn’t stop us beating the majority of them.
Who is to say that Tanganga, a former fullback and Anel, good at bringing the ball out can’t overlap? That gives a man advantage when you attack as you overload.
You also have a chance to dominate the midfield as you as 3 v 2 in that formation.
I don’t think one formation has a massive advantage over another. Whichever way you put it, each team has 10 outfield players.
Fact is, good defenders are cheaper than good offensive players. Right now, one maybe two centre backs and your system is good to go. You could even play Seriki, Tanganga, McGuinness, McCalllum and Burrows now; McCallum is very good in the air for his size and has played centre back for us.
In 4-2-3-1, we seemingly need one more centre back and one if not two wingers given we only really have Donovan and Chong, though Chong is down as an attacking midfielder rather than winger.
So it’s swings and roundabouts. It all depends what quality of players are available and how likely we are to get them. At the moment we are weak on the wing and favouring a system that relies on wingers.
