Throughout his career, Ronaldinho was praised by pundits in particular for his technical skills, flair, and creativity, as well as his exceptional first touch. With his pace, acceleration, athleticism, balance, ball control, and dribbling ability, he was capable of beating players when undertaking individual runs, often using an array of tricks and feints to get past opponents in one on one situations, including step overs and nutmegs. Physically strong in possession of the ball, Richard Williams writes "slender in build, the Brazilian has a strength belying the cartoonish smile". He also incorporated flashy moves such as back–heels, bicycle kicks, and no–look passes into his general gameplay. Among his repertoire of moves, is the "elastico", a move he learned by watching videos of one of his idols, the 1970s Brazilian star Rivelino. Ronaldinho came to be known as one of the best exponents of the feint, and in parts of Africa – especially Nigeria – this move is now called 'The Gaúcho' after him, due to his role in popularising the use of this particular skill.
