Liverpool have enjoyed a successful, albeit trophy-less, season so far this season.
With 97 points in the Premier League, though, they finished just one point behind champions Manchester City, becoming the highest points-gaining runners-up in history.
And in the Champions League, Liverpool have made it to their second successive final, where they’ll face fellow Premier League side Tottenham.
But Thompson, whose career at Liverpool spanned 13 years, believes his former club still need to strengthen this summer.
"No matter who you are, you have to strengthen while you are on top. Don't wait until things go wrong. It was always the way of doing things in our heyday,” he told Sky Sports.
“No matter what we won, we always brought in two players to strengthen and give more options on the field and regenerate the dressing room.”
Thompson then highlighted two areas in which the Reds should look to bolster.

"If Liverpool can, I would look at a creative midfield player and another striker," he added.
“Mohamed Salah, Sadio Mane and Roberto Firmino are the three, but it's a case of getting someone in who will be sitting on the bench for most of the season.
"It's like in midfield, we have a lot of players who are quite similar.
“We need someone with a creative spark and to give us more goals from that department.
