"I think this is a special day for me and my family", said the Croatian centre-half whose existing contract with Liverpool expires at the end of the 2018/19 season.
He has been a mainstay of Jurgen Klopp's defence this season, with Liverpool battling to secure a Champions League spot as the campaign enters its final weeks.
"We have got to go again and it is still in our hands".
"Against Watford we can change everything and get a good result".
Liverpool will be looking to win three successive Premier League away games under Jurgen Klopp for only the second time, with the previous occasion coming in October 2016.
Klopp said tying Lovren to a new deal, which Press Association Sport understands is for another four years with the option of a further 12 months, was key to their future progress.
"We still could have won the game, that's how it is. We need to defend as well as possible and use the chances we create".
Wrong. In reality, this outcome isn't as good as it first seemed.
To lose 2-0 to a relegation struggler that had to play most of the game with a man less is completely unacceptable, and Watford skipper Troy Deeney did not mince his words afterward.
What do we want then?
"When we saw the pictures it looked bad". I don't see their training. Atletico Madrid was victorious in the 2013-14 season, and like the other two giants, the Rojiblancos have translated their strong domestic form into deep runs in the UEFA Champions League.
All in all no outcome tonight will be a definite nail in the coffin for our season but tonight's game will highlight just how important our remaining games are.
With news of Steven Gerrard, Jamie Carragher, Steve McManaman and Daniel Agger's involvement in the game, some Reds fans had feared a significantly weakened squad would come down under to play Sydney FC on Wednesday, May 24 at ANZ Stadium.
