Nigerian international winger Ahmed Musa became Premier League champions Leicester City's second acquisition in a week on Friday for what is believed to be a club record fee of £16.6 million ($22 million, 20 million euros).

The 23-year-old, who announced his talent globally in scoring a brace against Lionel Messi's Argentina at the 2014 World Cup, signed a four-year contract in England, ending a successful spell at CSKA Moscow.

Musa, who CSKA asked too much for when Leicester asked about him in the transfer window in January, is the Foxes fourth signing of the close season.

Musa and former France Under-21 midfielder Nampalys Mendy, who joined from Ligue 1 side Nice on a four-year deal last Sunday for £13m, will bolster the Foxes squad for a tilt at the Champions League.
