Patrick Vieira praised Liverpool after his Crystal Palace were beaten 2-0 by the Reds in their second pre-season game in Singapore on Friday afternoon.
The Crystal Palace boss highlighted how tough of a task it would be to take on Jurgen Klopp's side who have 'challenged' for the Champions League and Premier League for the last 'five or six years'.
After losing their first pre-season 4-0 against Manchester United in Bangkok, Liverpool returned to winning ways before leaving their pre-season tour of the Far East. Liverpool will fly to Austria shortly for the next stage of their new season preparations.
