Klopp could write a book on Adam Lallana.
Adam Lallana left for Brighton and Hove Albion at the end of last season.
The 34-year old midfielder spent 6 years with the Reds, five of them playing under Klopp and won the Premier League in his last season with the Merseyside club.
He still remains a popular figure at Liverpool FC and Klopp prepares to welcome his former player back to Anfield.
Klopp said: “Our visitors today have many talented players but there is one we are very familiar with at LFC.
“I will have to stop myself saying too much on Adam Lallana because I could write a book. And I have to be respectful to the fact he is our opponent today… he wants to beat us and we him.
“But I must mention what a special person he was for us – and in truth remains so. When he left, I described him as a Liverpool legend for his contribution and I read somewhere recently he felt a little embarrassed by that. But he absolutely shouldn’t. It’s a status he has earned and then some.
“Thirty-six Premier League matches a season I look forward to seeing Adam play. There are two when I do not… today is one of those.”
