There is being derailed, but it would require such a big swing in the favour of Ipswich, Southampton and particularly Leeds that it’s barely credible.
I don’t have the PPG data, but take Southampton as an example. They need 14 points or more than us to overtake us. That’s the equivalent of winning 5 more games than us - which would be 25% of the remaining 20 fixtures. Not going to happen, particularly as now we are only seriously missing Ndidi who is a big miss, but not sure he’s a miss that size.
As we frequently demonstrate - and particularly at home - we can be in first and second gear and despatch most teams in this league. So I think we’ll be fine losing Ndidi for however long.
