Foster is the second player of the season to make a team of the week, with Clayton Ince being chosen last month.
Foster's week was described by the Football league:
"Foster was the sound foundation upon Crewe's 3-1 win over Nottingham Forest. Dario Gradi's men are desperate to prove they belong in the First division and it is young talent like Mansfield-born(??) Foster, with his tidy tackling and understanding of the game, will help them do so"
The team in full:
Mart Poom(Sunderland), George McCartney(Sunderland), Steve Foster(Crewe), Pablo Mills(Derby), Michael Jackson(Preston), Michael Tonge(Sheff Utd), Jim Magilton(Ipswich), Jim Bullard(Wigan), Danny Spiller(Gillingham), Robert Blake(Burnley) and Andy Johnson(Crystal Palace).
