Atletico Madrid defender Kieran Trippier has heaped significant praise on Liverpool ahead of the meeting between the two clubs in the Champions League next month.
The former Tottenham defender was part of the side that suffered defeat to Jurgen Klopp's side in the Champions League final in Madrid last season before sealing a move to Atletico.
Since that transfer, Trippier has been a regular in Diego Simeone's side and will lock horns with Liverpool once again in the knockout stages of the Champions League next month.
Liverpool, having reached the final in each of the last two seasons, are heavy favourites to advance from that clash and Trippier is aware that a stern test is on the horizon.
"Playing here has given me a good opportunity to watch nearly every single game in the Premier League and I've watched Liverpool a lot and seen for the last two and a half years how good they've been," he told the BBC.
"The players they have brought in, the manager, you see how they have developed, they have been fantastic and made two Champions League finals.
"This season has been fantastic and to be that far ahead in the Premier League, with how intense the Premier League is, it just shows what a good job Jurgen Klopp has done."
