I am that confident that we will beat United over 2 legs that I have booked my train tickets to London On Sunday 1st March while they are still reasonably cheap.
Managed to get a midday train which gets into Euston at 14.10 with the return leaving at 20.35 arriving back in Manchester at 22.55. Return price of £55.
I have previous form for taking a punt on cheap train tickets for a Wembley Final.
When City lost to Everton 1-0 (at Goodison) in 2016,I knew that we would overcome the deficit and win the 2nd leg and proceed to Wembley. So I booked my train to London the next day for about £40. Sometimes you just have to speculate to accumulate.
