West Ham United co-owner David Sullivan is reportedly looking to complete two signings before the end of this month, with the transfer window set to close on Friday.
The club have only made one signing this window with Darren Randolph returning for his second spell at the club, but new manager David Moyes is said to be keen on reinforcements.
According to the Evening Standard, Moyes is hoping to bring in cover at right-back and central midfield, with Pablo Zabaleta and Mark Noble in need of support.
The report adds that Nottingham Forest full-back Matty Cash and Slavia Prague midfielder Tomas Soucek have been linked.
West Ham spent £80m during the summer but have struggled this season and sit in 17th place in the Premier League table.
The club sacked former manager Manuel Pellegrini in December and were knocked out of the FA Cup at the weekend by West Bromwich Albion.
