Since 1999, Harry Redknapp has used the 4-4-2 in 371 Premier League games.
How many times has he used a 4-3-3? Only 13 times.
The 4-4-2 is a simple formation where the defenders defend, the midfielders create and the forwards score.
With a 4-3-3, there is a high emphasis on the full-backs to provide width because there are no wingers. You need the three central midfielders to play their roles accordingly and you need the wide forwards to work in tandem with the central forward.
At Chelsea, Daniel Sturridge wouldn't pass to Fernando Torres, Juan Mata would play as a de facto attacking midfielder and Torres wasn't consistently scoring.
Signing Eden Hazard looks good on paper but it does pose a tactical quandary for Tottenham Hotspur.
Especially when Hazard doesn't do enough defending, meaning you cannot risk playing him out wide.
Just like Redknapp refusing to play Rafael van der Vaart out wide against Everton:
You couldn’t play Rafa van der Vaart out there because Leighton Baines would have run forward and Rafa would have had a problem chasing him all day if you stuck him wide right.
