Fabinho was signed at the end of May from Monaco by the Reds for a fee of up to £43.7 million as reported by the Telegraph, with Keita joining for £52.75 million after RB Leipzig could only qualify for the Europa League, according to the Liverpool Echo.
There is a high chance that both players will be picked to start games from the off next season under Jurgen Klopp, and with Jordan Henderson the club captain, who is playing well for England at the World Cup, the midfield is seemingly quite predictable at the moment for 2018/19.
It could be be bad news for injured star Alex Oxlade-Chamberlain, who had been putting in some excellent performances up until his unfortunate knee injury against Roma in the Champions League semi-final first leg.
It had been a difficult start to life for Oxlade-Chamberlain at Anfield following his January move from Arsenal, but he started to show consistency towards the end of the season.
The signings of Keita and Fabinho coupled with his injury could seriously count against him in terms of his long term starting prospects, which would be a shame for a player who was undoubtedly improving with every game.
According to a recent report from the Liverpool Echo, Chamblerlain will return to action around November which frustratingly for him, will give Henderson, Keita and Fabinho plenty of time to become Jurgen Klopp's go-to midfield trio, reducing the 24-year-old to substitute appearances once more.
Then there is the prospect of Klopp making further signings, with the Nabil Fekir links refusing to disappear for good, which will make Chamberlain's spell on the sidelines all the more frustrating.
