Liverpool legend John Arne Riise is concerned that his former club are not 'strong enough depth-wise' to keep with Manchester City and Chelsea in the Premier League title race.
Jurgen Klopp's Reds suffered a setback last week in their quest to reclaim the top-flight title, losing 3-2 away to West Ham to slip to fourth in the table - four points behind leaders Chelsea.
It was Liverpool's first league defeat in 25 matches, with the Reds just clinging on to a top four spot at the back end of last season - but Riise believes Klopp's men could continue to struggle should an injury crisis emerge like it did last season.
