Sources in Germany have told SunSport the attacker was keen on a return to the Premier League after two years in the Bundesliga with Wolfsburg and Borussia Dortmund.

A loan deal with an obligation to buy the German international for £26million was proposed to the Hammers, 24 hours before deadline day.

German sources claim the Hammers took their eye off the ball on the final day of the window.

The confusion surrounding a proposed move for Sporting Lisbon midfielder William Carvalho ensued while Schurrle was left in limbo.

Club co-chairman David Sullivan said: “It’s no secret that we made a club record bid for William Carvalho, but unfortunately that offer was rejected.”

The 2014 World Cup winner has failed to make an impact since moving to Dortmund last summer for £18m.
