Tottenham boss Mauricio Pochettino refused to comment on the club's approach for West Brom striker Saido Berahino but admitted he would like to strengthen his attack before the transfer window closes.

"I am not going to speak about our private business," the Argentinian coach said when asked directly about interest in Berahino.

"It is obvious we need to add some more (players) in our offensive positions. We identify our targets and the chairman (Daniel Levy) is working very hard to bring new players in this position, but I am happy with my squad."
