Ange Postecoglou's Celtic rebuild has entered its second phase as the summer transfer window opens.
The Parkhead boss exceeded expectation in delivering both the Premiership title and Premier Sports Cup last season but is adamant he's just getting started.
Up next is a crack at the Champions League as Celtic go straight into the group stage.
And with both Tom Rogic and Nir Bitton departing at the end of last term, midfield recruits are a priority.
On Friday, a report in the Daily Mail named Brazilian midfielder Vinicius Souza as a potential loan option.
Here, Record Sport Online takes a closer look at the 22-year-old.
Who is Vinicius Souza?
Born in Padre Miguel, Rio de Janeiro, Souza joined Flamengo's U-15 side in 2014, rising through the ranks to become a first team player in 2019.
He made his senior debut against Vasco da Gama in March that year and was promoted to the first team squad full-time at the beginning of the following season.
Ahead of the 2020/21 season, he signed for Lommel, the City Group's Belgian club, who operate in the second tier.
He was loaned upwards to top-flight side Mechelen the following year, an unusual move but one which suggests the City Group have a clear plan in place for his development.
He is said to be 60 per cent owned by the parent company behind the likes of Manchester City and Yokohama F. Marinos, from whom Celtic plucked Postecoglou last summer.
What would he bring to Celtic?
Standing at 6ft 2, Vinicius is an intimidating presence and with 11 yellow cards and a red to his name last season, it's clear he's not afraid to put his considerable frame to use.
But the South American is not some flat-track bully, although he is sharp and strong into the tackle.
He prefers to operate from deep and is adept picking forward passes to move his team forward.
And, as is key in the middle of the pitch, Vinicius protects the ball well in possession - but not just using his size. His close control is neat and tidy and that allows him to escape tight situations with relative ease.
While spraying passes appears to be his preference, he's displayed the ability to burst forward rapidly with the ball, often immediately after winning it back to quickly to launch a counter-attack.
Vinicius played 35 times for Mechelen last term, scoring twice for a team which finished 7th in the Jupiler Pro League.
Given Celtic's dominance in Premiership matches, it wouldn't be a stretch to predict he could increase those goalscoring numbers in Scotland.
Overall, Vinicius would add a different dimension to Celtic's midfield, which while populated by a number of technically gifted footballers, arguably needs an injection of athleticism if they are to compete in the Champions League.
Postecoglou 's side were physically outmatched in midfield by Bodo/Glimt in the Europa Conference League last season and this could be a signing priority formed with those two matches in mind.
Who else is interested?
The Daily Mail report names Fenerbahce, Club Brugge and Bologna as having "declared an interest", so the player will likely have no shortage of options over the coming weeks.
Interest from Brugge, the Belgian champions, is perhaps notable as confirmation Vinicius made a serious impression in the league.
But with Celtic's head of recruitment Mark Lawwell joining from the City Group earlier this year, the Premiership champions could have the edge in negotiations.
What's been said about him?
Former Flamengo boss Jorge Jesus took a keen interest in Vinicius and promoted him to the first-team permanently following his arrival in 2019.
Jesus was said to have likened the youngster to one of his former stars at Benfica - Nemanja Matic.
Matic was a relative unknown when he arrived at Chelsea in 2009 and he left just two years later before returning in 2014 to become a key man during a successful period for the club, later being regarded as one of the finest Premier League midfielders of that time.
A report from Goal notes Jesus likened Vinicius to the Serbia international and took him on as a "personal project".
An ageing Matic became a bit-part player at a poor Manchester United side but in his prime married physical dominance with fleet footed technical ability and a brilliant eye for a pass.
Even with limited viewing of Vinicius' game the comparison makes sense - the pair do share similar qualities and if there was anyone qualified to make such a comparison it was Jesus, who had a considerable hand in developing Matic.
Perhaps crucially for a club like Celtic, where the sky-high demands can be overwhelming for players, Jesus was said to be particularly thrilled by Vinicius' "personality" on the pitch.
It appears Postecoglou would be recruiting not only a strong footballer, but a strong character, too.
