Arne Engels has set his sights on steering West Ham back to the Premier League after his transfer from Celtic was confirmed.
The Belgium international, who has put pen to paper on a five-year deal, moves for a fee which Standard Sport understands could rise as high as £25m if add-ons are met. That makes him the most expensive signing in Championship history, beating the £20.8m Burnley spent to sign Florentino Luis in July.
