Conclusion

Several horses fit the bill for seven of the criteria mentioned above. However, just one fits for eight and this is ANIBALE FLY.

Finishing fourth in the race last year, the JP McManus-owned gelding is only let down by the fact that he is already 12/1 second favourite in the market and is not 25/1+, and this is the weakest of all criteria due to the fact only 7 of the last 12 winners were above the given threshold. The nine-year-old has all the ingredients to win the 2019 Aintree showpiece.
