Being a Portuguese I can tell you that Cristiano Ronaldo is a WINGER, not a Striker.

In the last 10 years our SOLE striker was:

Pauleta
or
Postiga
or
Liédson
or
Hugo Almeida
or
Edinho

Never any of them in pairs, let alone trios.

[Celtic]

Teams in Portugal, like in any normal football practicing nation, play with 1 striker:
