Frank Lampard has hailed Olivier Giroud as “the ultimate professional” in the wake of his four-goal Champions League salvo at Sevilla.

France striker Giroud notched a perfect hat-trick then added a penalty as Chelsea sealed top spot in Group E with a game to spare by thrashing Sevilla 4-0 in Spain.

Giroud’s left-foot, right-foot and headed goals sealed that perfect treble, before the 34-year-old dispatched a nerveless spot-kick at the death.

“It’s having a top player playing with quality and playing with dedication.

“It was an amazing performance from Oli, to score four goals at this level, Champions League level, against a really good opponent.

“The individual quality of all his goals, I know the last was a penalty, but the team quality and his individual input, rightly he gets a standing ovation as he comes off the pitch. And I’m delighted for him.”
