Having signed Red Bull Salzburg flyer Sadio Mane over the summer, Southampton were reportedly interested in adding another speeder in Kennedy Igboananike.
The 25-year-old Nigerian, who was playing with AIK in Sweden, had earned a reputation for his rapid pace, and it was reported in November that Southampton were battling with QPR for the signature of Igboananike.
Their pursuit of Igboananike resembled that of Mane and Mayuka, in trying to unearth speedsters from unheralded European countries - but he won't be coming to the South Coast.
"Kennedy is a dynamic goal scorer with a track record of producing," said Yallop. "He’s young and exciting, a player with incredible pace, and we look forward to adding him to our roster to bolster our attack."
With speculation linking Southampton with moves for Andros Townsend and Danny Ings, it may simply be a case of manager Ronald Koeman searching for more illustrious players.
This is Igboananike's first move away from Sweden since arriving in 2007 with Djurgardens, and it remains to be seen whether he will finally reach the Premier League.
