Sadio Mane could be confirmed as one of Liverpool's most expensive signings on Tuesday after he completed his medical on Merseyside.
The 24-year-old forward underwent a series of tests and scans at the Spire Liverpool Hospital in the city before sitting down with club officials to thrash out personal negotiations.
As a result Mane's switch from Southampton will not be completed until Tuesday at the earliest, although there is a chance discussions could drag things out until Wednesday.
The transfer fee is believed to be at least ?30million, which would make Mane one of the top three most expensive signings in Liverpool's history.
Currently, the Reds' record transfer is the ?35million paid to Newcastle for Andy Carroll in 2011, while Christian Benteke was a ?32.5m signing from Aston Villa last summer.
Senegal international Mane, who scored 25 goals in 75 appearances for the Saints, will become Jurgen Klopp's fourth signing, having already brought in centre-back Joel Matip, midfielder Marko Grujic and goalkeeper Loris Karius.
Liverpool's players who have not been involved in the European Championships are due to return for pre-season training on Saturday, with their first friendly the following Friday.
