Neil Lennon had his head in his hands on Sky Sports' Soccer Special as Thiago's sensational second-half strike put Liverpool 1-0 up against Porto in the Champions League.
The Spaniard scored his second goal for the Merseyside club as Jurgen Klopp's side maintained their 100 percent record in the competition so far this season.
Thiago's strike has earned him plenty of praise across the football world, and the former Celtic manager couldn't quite believe what he was seeing.
"Oh my goodness what a goal!" Lennon said on Sky Sports in disbelief.

"What a finish. Thiago comes onto it on the half-volley and he sends an absolute beauty low into the corner.
"I cannot tell you how difficult the tariff for this skill is. It is magnificent.
"[Diogo] Costa, absolutely no chance, he probably couldn't see it till late. It's totally against the run of play because Porto have missed two unbelievable chances.
"But this is caviar Jules [Julian Warren], it's gone through the legs of [Fabio] Cardoso as well, that is absolutely magnificent."
The Liverpool boss also hailed Thiago's effort post-match, saying goals like that 'don't happen often'.
Klopp told reporters: "Whoever sees Thiago in training knows he has the technique to do it but even with this technique it doesn’t happen constantly that he can fire such a thunderball."
