article: Jurgen Klopp rejected the overtures of West Ham United after handing in his notice at Borussia Dortmund. No matter, it was worth a try. Now on to the next one. If Rafael Benitez wants to return to English football after leaving Napoli maybe he can be persuaded to take over a project that includes a move to the iconic Olympic Stadium in a year's time. West Ham need a coach of high ambition to underline the size of the venture. Sam Allardyce isn't that man. He had his chance and did not take it. Allardyce has often talked of the qualities he could bring to an elite club, but the momentum of his season changed on Boxing Day when he left his best players out of the starting line-up at Chelsea, and lost. Sam Allardyce is not the man to lead West Ham into their new exciting adventure at the Olympic Stadium . Allardyce (left, pictured behind Manchester City manager Manuel Pellegrini) has not been up to scratch . Click here to read chief sports writer Martin Samuel's brilliant column on Jack Grealish . The folly of resting key individuals for such an important game over the Christmas period was exposed as West Ham then played two home fixtures, losing to Arsenal and drawing with West Brom. If West Ham had maintained their form going into the Chelsea game — 31 points from 17 matches — they would now be fifth in the league. Had their form since that day been played out through the season — 12 points from 16 games — they would be bottom. Allardyce's reputation is that of a man who guarantees survival, but since Christmas West Ham have been playing relegation football. If a new manager is being considered, it is understandable. West Ham must go to the Olympic Stadium with more on their minds than survival. Rafael Benitez could return to English football after Napoli and may be persuaded by the Hammers project .
