West Ham are expected to confirm the permanent signing of Manuel Lanzini in the next few days.

The 23-year-old midfielder has been on loan at West Ham from UAE club Al Jazira and has impressed sufficiently for manager Slaven Bilic to want to tie him to a permanent contract.

The fee for the Argentine is expected to be £7.4million. A deal has been in place for several weeks, but West Ham wanted to confirm his fitness after a thigh injury.

He is expected to play at Chelsea on Saturday.

Meanwhile, West Ham have agreed to sign Norway midfielder Havard Nordtveit on a free transfer from Borussia Moenchengladbach next season.

The 25-year-old will leave the Bundesliga side at the end of the season, with the club confirming on Twitter that he would move to the Premier League.

"Havard Nordtveit will not extend his contract expiring in the summer and move to England.”
