The 34-year-old penned a one-year deal at the Hawthorns earlier in July following the conclusion of a short stint at Juventus, and his new team-mate is delighted with his fitnessGareth McAuley believes new West Brom team-mate Nicolas Anelka is already proving a valuable addition to the squad.
The Frenchman signed a one-year deal at the Hawthorns on July 4, after spending the second half of last season at Serie A champions Juventus.
And McAuley claims the 34-year-old remains in good condition, and will prove to be a valuable asset for Steve Clarke's side.
"In fairness, he's a real athlete," the Northern Irishman told Birmingham Mail. "He looks like he's cruising through. In training he's been sharp, his awareness is another level and he still has a turn of pace.
"He's been lively in training and he has that pace. He's only switched it on a couple of times when he needed to but, when he did, he was away."
The 33-year-old believes the presence of the former Manchester City, Chelsea and Liverpool striker will boost the club ahead of the new season.
"It gives everyone a lift, especially all the young players, to see someone of his level, who is still as sharp and hungry," he continued.
"It's a great signing and maybe he can score us a few goals."
