I have a bet currently running, it's a £100 double, Notts county to win league one and Man city to come top without the big 4, if it comes in I will win £1700 the County bit is in the bag just City to go, so should I stick £500 on Spurs to get 4th at 4/5 to garauntee winning £400 and making a £300 profit but if they don't costing myself £500 from £1700, safety or nuts out???
