Jurgen Klopp insists he is “excited” by the challenge Liverpool face as their injury list mounts.
The Reds confirmed on Friday that key defender Virgil Van Dijk has undergone successful surgery on the knee ligament injury he suffered against Everton earlier this month.
And Klopp’s problems intensified when Fabinho, Van Dijk’s defensive replacement, sustained a hamstring injury which will rule him out against West Ham on Saturday evening.
Klopp concedes Liverpool’s packed fixture schedule makes them susceptible to picking up injuries, but he is ready to embrace the challenge.
“Antonio has had sensational season so far and if they miss him it doesn’t help,” he said.
“But even if you don’t know him so well in England, Haller came from Germany and played an incredible two seasons at Frankfurt.
“He is a different type but he is a good footballer, quick, physically strong in the air, and they have different options because West Ham did some smart business.
“It looks like it’s all starting to click really. David Moyes is doing a really good job and we will face a proper fighting unit. One player less will not make it easier for us.”
