Dejan Lovren earns £100,000-per-week at Liverpool, just let that sink in for a minute.
He also cost the Reds £20 million back in 2013, which based on today's performance against Tottenham was £20 million too much.
Harry Kane's fourth-minute opener and Son Heung-min's goal both came after mistakes from the Croatian, who was replaced by Jurgen Klopp in the 30th minute.
Lovren, to the amazement of Liverpool fans, tried to play offside from a thrown-in, which allowed Kane to beat Simon Mignolet and find the back of the net.
Eight minutes later and Lovren completely mistimed a header on the half-way line to put Kane through on goal again. He squared for Son instead to make it 2-0.
Klopp had seen enough and on the half hour mark he threw on Alex Oxlade-Chamberlain to end Lovren's nightmare at Wembley.
Oxlade-Chamberlain's arrival injected even more pace into Liverpool's attack but defensive errors continued to plague the Merseysiders.
Dele Alli made it 3-1 just before the break and Mignolet produced a customary mistake of his own to gift Kane his second of the game.
Speaking after the game, Graeme Souness summed up Liverpool's performance by saying "you're only as strong as your biggest weakness", which he identified as Lovren.
Liverpool fans reacted to Lovren's performance by saying he should be sold, but the question that needs asking is who decided to sign him in the first place?
Well, it was Brendan Rodgers that brought the 28-year-old to Anfield back in 2014, but Jamie Carragher has been getting some flack on social media for Lovren being at the club.
In the tweet below, one fan basically blames Carragher for being the one who recommended Lovren to Liverpool in the first place.
But Carragher was having none of it. In response, the Sky Sports expressed confusion at why everyone thinks he was responsible for Lovren's signing three years ago.
He wrote: "Where has this come from? I get tweeted this all the time! I did a piece on him on MNF when he was outstanding at Old Trafford for Soton!!"
Clearly Carragher doesn't want anything to do with Lovren's arrival - and who can blame him?
Lovren has made too many mistakes to count at Liverpool in his three years at the club and it's about time Klopp realised he's the weak link in his side.
