Sam Allardyce was in Belgium on Sunday to cast an eye over Anderlecht's Cheikhou Kouyatè and Standard Liege’s Michy Batshuayi.
The pair went head-to-head as Anderlecht took on Liege and Allardyce is understood to be keen on both, according to the Daily Telegraph.
Kouyatè, 24, is a Senegalese centre-back who joined Anderlecht from Brussels in 2008 and has since made over 166 league appearances for the club, as well as playing in the Champions League.
The 6ft4in defender has won four caps for Senegal as well as representing his country at the 2012 Olympics in London.
Batshuayi is a 20-year-old striker who has scored 20 league goals in 32 starts for Standard Liege this term.
The Brussels-born forward has won eight Under-21 caps for Belgium, scoring five times.
There is understood to be a buy-out clause of £6.5m in Batshuayi’s contract, with Arsenal, Spurs, Everton and PSV Eindhoven all believed to be interested in the striker.
