West Ham have enquired about Bayern Munich right-back Noussair Mazraoui and confirmed their interest in Leeds United winger Crysencio Summerville but remain divided on their valuation.
Mazraoui, 26, has spent two seasons at the Allianz Arena, having joined on a free transfer from Ajax in the summer of 2022.
The full-back came through the ranks of Ajax, where he played under current Manchester United manager Erik ten Hag.
He was also a member of the Moroccan national team that overcame adversity to reach the semi-finals of the 2022 World Cup.
There were reports that United were circling the player, but now West Ham have expressed interest.
West Ham have submitted a bid for Leeds United winger Crysencio Summerville
Fulham are also interested in Summerville, who has impressed for Leeds since becoming a regular starter two seasons ago.
The winger is coming off a brilliant campaign, in which he provided 21 goals and 10 assists in 49 appearances in all competitions.
It was a season that ended in disappointment when Leeds were beaten in the play-off final at Webley by Southampton.
Summerville, who has won an international cap for the Netherlands at under-21 level, joined Leeds from Feyenoord in September 2020.
West Ham, now managed by Julen Lopetegui, have made three major signings so far in this transfer window.
Promising youngster Luis Guilherme joined the club from Palmeiras, while goalkeeper Wes Foderingham arrived on a free transfer following his departure from Sheffield United.
West Ham also secured the signing of Max Kilman from Wolves, who will bolster their defensive ranks.
