Mohamed Salah began life at Liverpool with tours of Melwood and Anfield.
Even with the vast wealth of the Premier League, £70m feels like an excessive valuation but Liverpool would be buying potential - with Keita just 22 - and a player who has been personally requested by Jurgen Klopp.
22-year-old Keita is seen by Klopp as the all-action midfielder his team needs, combining power, energy and passing ability.
Salah is only one player, and while bringing his significant talents to Anfield is a good start, the Reds still have a long way to go to provide the kind of depth they need to successfully compete across four fronts.More news: Eight-time champion Federer eases into 13th Halle semi-final

Salah joins a Liverpool squad packed with talented forwards, ensuring that competition for places in Jurgen Klopp's starting XI will be fierce, something Milner feels is crucial of the club is to taste success this coming season.
"I'm very excited to be here".
He was a key figure as Roma finished second in Serie A last season, scoring 15 goals in 31 league appearances. "I am happy to be here and I really want to win something for this club". "I have followed him since he emerged at Basel and he has matured into a really good player".
Salah covered an average of 51m per game in counter-attacking dribbles for Roma, compared to 26m per game for Liverpool's own speedy attacker Sadio Mane and just 12m per match for Philippe Coutinho.
"The way we play, you can't have any passengers", Milner said, as quoted by the club's official website.
