Sadio Mane and Dusan Tadic are hoping to provide the midfield goalscoring firepower that Ronald Koeman craves.

The attacking duo, signed this summer for a combined £21m, are expected to replace the goals provided by the likes of Adam Lallana, as well as Jay Rodriguez while he continues to recover from his ACL reconstruction.

Mane and Tadic both have fine scoring records with their previous clubs.

While Tadic has already shown glimpses of his ability as he settles into life at Saints, Mane remains an unknown quantity to supporters.

However, his record is mightily impressive since joining Salzburg in 2012.

In his first season with the club, he bagged a whopping 19 goals in 29 games.

He followed that up the following year with 23 in 50 appearances and had already bagged three goals in eight games this season before sealing the move to Saints.

It means a hugely impressive haul of 45 goals in just 87 games for Salzburg, just better than a goal every other game from midfield.

The standard of football and defences to compete against in the Austrian Bundesliga are clearly inferior to those in the Premier League, with Salzburg netting 110 goals in 36 games as they won the title by 18 points last season.

Mane, though, has also scored plenty of goals for Salzburg in the Europa League.

He has bagged five in 15 appearances for Senegal as well, suggesting the 22-year-old’s abilities are transferable beyond just Austrian football.

Tadic, meanwhile, also has an impressive record.

At Vojvodina in Serbia he scored 31 goals in 126 appearances over the course of four seasons before he switched to play in the Eredivise in Holland.

In two seasons at Groningen he netted 14 times in 76 appearances and then bagged a remarkable 32 goals in two seasons – just 85 appearances – at FC Twente, prompting Saints to move to secure his talents.

Lallana had secured double figures in four of his last five seasons at Saints to have provided valuable goalscoring back-up from midfield, although the first two of those seasons were in the third division.

Rodriguez was Saints’ top scorer last season with 17 in all competitions prior to his campaign-ending injury at Manchester City in early April.
