Kagawa’s biggest weakness is his defensive ability, as he is weak at tackling and intercepting. So in a 4–4–2 formation, Kagawa would be an immense liability.
The major problem of course is that Sir Alex Ferguson loves the 4–4–2 formation. Throughout his managerial career, Sir Alex has employed this formation extensively, and almost all of the games this season have seen Sir Alex use this formation.
Nevertheless, I think that a change to a 4–2–3–1 formation or a 4–3–3 formation is necessary to adapt to the modern game. In 2010, none of the winners of the Spanish, English and Italian Leagues, as well as the Champions League, relied on the 4–4–2.
If you look at the finalists in this year’s Champions League, both Chelsea and Bayern Munich employ a 4–2–3–1 formation.
Sir Alex is not a big fan of this formation, but to challenge for Europe and also on the domestic frontier, some tactical versatility in formations is indeed required.
However, Kagawa can also be incorporated into the United squad in a slight modification of the 4–4–2, the 4–2–1–1, where he can play “in the hole” behind the main striker.
