Pele for me. As said previously, took over when we were in a pretty precarious state, he brought in some fantastic players he knew from the Highland League (McArthur, Teasdale, Thomson, Stewart etc) and had us playing absolutely magnificent football. Going up the divisions he had a great eye for a player who'd been released from a 'big' club and unearthed some cracking players (Wyness, Robson, Sheerin etc).
Also, the fantastic team spirit, attacking football, brilliant comebacks and cup shocks/runs. The man is an absolute legend. there is only one Pele.
As for the others, Robbo won the league and the Bells Cup and has to be considered second best. Brewster was fortunate to inherit a side who knew how to play together and added a few tweaks. Charlie is doing well but it's hopefully early days and Baltacha was *****.
