Where did it all go wrong for Haller at West Ham?
There are a number of reasons why Haller struggled to excel at West Ham United.
The Frenchman predominantly played as a lone striker and given his lack of pace he was often ineffective.
His debut season was underwhelming due to a paltry return of seven league goals in 32 appearances and, most recently, he failed to seize his opportunity when Michail Antonio was sidelined with a hamstring injury.
Haller’s lack of work rate and being easy to mark against were other contributing factors in the decision to let him join Ajax.
Why did Haller want to go?
Haller previously played for Ajax manager Ten Hag at Utrecht between 2015-17.
Ten Hag certainly knew how to get the best out of him, with the striker scoring 30 goals in 65 Eredivisie appearances.
It is understood that Haller wishes to reunite with Ten Hag and bring his difficult spell in the Premier League to an end.
Who else are West Ham hoping to move on?
West Brom are in advanced talks with West Ham over a move for Robert Snodgrass.
Snodgrass, 33, has made just three Premier League appearances for West Ham this season.
His contract expires in the summer and The Athletic understands West Brom have offered the retired Scotland international an 18-month contract.
