Johan Cruyff thought he was best on the wing...
It's interesting how formations have changed over the years. When I grew up watching our 80s side, it was always two strikers - a partnership up front. We had Heath and Sharp, Gray and Sharp, and Lineker and Sharp. Cottee and McAvennie was the feared Hammers variant. Rush and Dalglish, of course, was legendary. Archibald and Crooks, Withe and Shaw, Mariner and Brazil...
I almost feel like I sleptwalked through the last 40 years. One up front would have been considered massively defensive in the days of peak Serie A when the greatest strikers in the world struggled to score. Indeed, there was a reason Maradona and Platini dominated the scoring charts in Italy rather than Rummenigge or Elkjaer. The front-man was marked to within an inch of his life. You needed to go further out the pitch to see any freedom. In England, this would have been considered cowardy defensive nonsense. Nowadays, few strikers in England score many goals. Most of the summer signings have flopped...for everyone.
I'm actually not convinced that one up-front is here to stay. I think, like long throws, two-men strike forces will slowly return...and be heralded as innovative tactical masterstrokes when they do...
