The Hammers are joined by Crystal Palace, Manchester City, Newcastle, Norwich City and Tottenham in holding an interest in the Dutchman.
Botman has also attracted admirers in Serie A and the Bundesliga having seemingly been close to a move to Liverpool during the January transfer window.

The report adds that the French Ligue 1 champions would be willing to part ways with the 21-year-old should bids of £27million be forthcoming.
Botman enjoyed an impressive Under 21 European Championships with Holland – earning a 7.05 average Sofascore rating from four outings.
That form followed 47 appearances for Lille across all competitions, including eight in the Europa League.
READ WEST HAM VERDICT
Valued at £25.2million and under contract until 2025 (Transfermarkt), signing Botman for the mooted £27million would be a bargain.
Clearly a player of incredible promise given the levels of interest, the young Dutchman could potentially be a Hammer for years to come if David Moyes can make the deal happen.
Having bizarrely turned up as a goalscoring centre-forward on two occasions for Ajax at Under 17 level, Moyes could utilise the 6’3 ace in more than one capacity.
