The former England international was impressed with how quickly the 25-year-old opened his account in the Premier League with the Frenchman scoring three goals in as many games already.
Haller became the Hammers’ club-record signing in the summer, with the Evening Standard reporting the deal could eventually rise to £55million.
“Haller’s been exceptional,” Mills said.
“He’s come in and hit the ground running, looks like the real deal, continuing that form he’s shown in Germany.”
“I think it’s so important players come over to be able to get off the mark quickly. It’s absolutely vital. He’s big, he’s strong, he’s got all the great attributes for the Premier League.”
Haller has certainly lived up to the hype that surrounded him when he arrived in the summer. Last season, the 25-year-old was involved in 24 goals, and Manuel Pellegrini will have been expecting results after splashing the cash. The Frenchman has highlighted great physical prowess when leading the line, winning 5.7 aerial duels per game so far this season [WhoScored] – something that has been missing for many years in East London. As well as that, Haller also averages three shots on goal in each outing [WhoScored], and if he continues at that rate, the goals will surely continue to come. The physicality that Haller has brought to West Ham has helped players such as Felipe Anderson and Manuel Lanzini flourish too, with the big Frenchman taking the pressure away from them in the final third. Their creativity will be vital in helping Haller continue to score goals, and so far all the signs are positive for the former Frankfurt forward to succeed in the Premier League.
