Do you judge managers by their trophy-winning success or by their ability to nurture talent? That question will likely influence your opinion in deciding the greatest boss in West Ham United's history and Sky Sports wants your choice. From three candidates of Harry Redknapp, John Lyall and Ron Greenwood, you can have your say and vote in our poll to establish the best of the bunch. We will then announce the winner in the week commencing 12th August.
Harry Redknapp (1994-2001)
Redknapp spent seven years at West Ham and played a key role in bringing through a number of promising youngsters, including Rio Ferdinand, Michael Carrick, Frank Lampard and Joe Cole. He also recruited the likes of Stuart Pearce, Trevor Sinclair and Hammers legend Paolo di Canio. Redknapp led them to fifth place, the club's second best league position in their history, in 1999 and won the Intertoto Cup with the Hammers the following season.
John Lyall (1974-1989)
In 15 years with the Hammers, Lyall won two FA Cups, reached the Cup Winners' Cup final and achieved the club's highest league finish of third. The second of the two FA Cup wins in 1980 saw Lyall's side overcome Arsenal to become the last team to win the competition when outside the top flight. Relegation from England's pinnacle division in 1989 saw Lyall sacked after 34 years, in all, at the club.
Ron Greenwood (1961-1974)
Greenwood was in the West Ham hot seat for 13 years and brought great success to the club. He was in charge of the likes of Bobby Moore, Martin Peters and Geoff Hurst, helping to develop them as players ahead of England's 1966 World Cup win. Before that, however, Greenwood had already led the Hammers to their first major trophy wins - the FA Cup in 1964 and the Cup Winners' Cup in 1965. They also reached the League Cup final in 1966. Greenwood moved upstairs to become general manager in 1974 before taking up the England job in 1977.
