Abstract: | Let Σ ⊂ R
3 be a smooth compact connected surface without boundary. Denote by A its second fundamental form and by Å the tensor A−(tr A/2)Id. In 4] we proved that, if ‖Å‖
L
2 (Σ) is small, then Σ is W
2,2-close to a round sphere. In this note we show that, in addition, the metric of Σ is C
0–close to the standard metric of S
