Liverpool face Barcelona over two legs in the semi-final of the Champions League next month, looking to reach the final for a second season running.
The tie will be the Reds' biggest test of the competition so far and Jurgen Klopp must find a way of stopping Lionel Messi if his side have any chance of progressing.
One player Klopp is more familiar with, and you'd think would know how to contain, is Philippe Coutinho.
The Brazilian played under Klopp at Anfield before pushing through a £142million transfer to Barcelona back in January 2018.
Coutinho was recently back in the UK for Barcelona's Champions League quarter-final clash against Manchester United.

Suarez is confident he won't get booed this time around in the UK when he returns to Liverpool to take on his former club next month.
The striker is also confident that Coutinho will get a good reception too.

Speaking to the Daily Mail, Suarez said: "Not at Anfield. In fact not in English football in general.
"When I went to Manchester United they whistled me of course! But your own fans… it's very unlikely that you hear that."
