Define “extremely wet”. Will it be as wet as the pre-season friendly at Nuneaton Boro in about 2015? That was like sheet rain and flooded the pitch in about 5 minutes.
Thats where having a fuller squad comes in handy. Last 3 seasons he’s averaged 34 games (albeit only 24 starts) but if you have Palmer/Sakamoto to step in and pick up the workload it should be ok.
