The midfielder has signd a four-year deal with the reigning Premier League champions, becoming the Reds’ second summer signing after Greek left-back Kostas Tsimikas.
And in a huge boost to Jurgen Klopp, his new £25m signing will be available to him for this Sunday’s clash against Chelsea at Stamford Bridge.
At one stage it appeared the Spain international would have to wait for his debut.
According to Premier League rules, players must be registered by their clubs by 12pm on the Friday before the weekend’s fixtures.
As a result, the relevant paperwork needed to have been completed by midday today [Friday, September 18] for Thiago to make his league bow against the Blues.
This ruling left the Reds with in a race against time to complete the signing of Thiago if they wanted him to feature against Frank Lampard’s side and it appeared they had lost the battle as he was announced long after the 12pm registration deadline.
However, as revealed by the Liverpool Echo, Thiago’s paperwork was filed before the noon deadline and Thiago is eligible for the Reds’ trip to the capital.
Furthermore, Klopp has hinted that the 29-year-old will be in his matchday squad.
“If they watch LFCTV this afternoon, he will train!,” the German tactician revealed. “You meant the match…we will see. I didn’t make the squad now for Sunday. We will see what we can do.
“I didn’t meet him now, we had only phone calls and exchanged messages. So, let’s have a look how he feels.
“Around a transfer like this the days are pretty busy with things you usually don’t do. If he looks all right, we will find the right place for him.”

In terms of Liverpool injuries, Tsimikas, Xherdan Shaqiri and Alex Oxlade-Chamberlain are set to miss the match against Chelsea.
It’s an intense week, a few little things here or there but should be okay,” Klopp said in his pre-match press conference.
“Nobody is coming back and the rest we will see. Two days to go, two training sessions but everything seems okay.”
