In the eternal debate about whether or not a manager should field a No 10, Manchester United and Arsenal are — in the context of the Premier League’s apparent “big six” — at opposing ends of the spectrum.
The other four managers are somewhere in the middle. Jurgen Klopp is a sceptic, often implying that gegenpressing is his equivalent of a No 10, and generally using 4-3-3. However, Liverpool do sometimes use a 4-2-3-1, with Roberto Firmino behind a proper striker.
Pep Guardiola also prefers 4-3-3, but this season has increasingly used Kevin De Bruyne in a No 10 role behind a striker, effectively illustrating that Manchester City are increasingly reliant on his brilliance.
Elsewhere, Chelsea head coach Frank Lampard sometimes uses a player in that role, and seems likely to switch between a 4-2-3-1 and a 4-3-3 this season. Jose Mourinho does something similar at Tottenham Hotspur. Those sides chop and change systems.
Manchester United and Arsenal do as well, in different ways, but there’s effectively one constant. United have completely committed to playing a No 10 — Ole Gunnar Solskjaer has unashamedly based his side around Bruno Fernandes. Arsenal have totally turned away from using a No 10, with Mikel Arteta omitting Mesut Ozil from their Premier League squad.
To simplify things: United are trying to create through individual brilliance, Arsenal are trying to create through their structure. Sunday’s game between them at Old Trafford showed both sides of that approach.
