West Ham United won't name Portsmouth boss Avram Grant as new manager until next month.

The Sun says the former Chelsea and Portsmouth chief is expected to take over at Upton Park on June 1.

He will replace Gianfranco Zola, axed after a disappointing season in which the Hammers finished just one place above the relegation zone.

Grant's appointment will see him team up again with former Stamford Bridge colleague Steve Clarke.
