I changed my captain to Rooney in advance of GW2. This shows on the transfers screen...but Carroll still shows on the scores screen. Any idea what I might have done wrong?...email address to query?

The GW runs Tuesday to Monday, so the Captain you had over the weekend is the same you had carried over to tonights game

Sorry if I'm being thick - I'm from FPL land
Are you saying I need to change captain on Tuesday for a GW which actually begins on Saturday?

No, you have any time until the first kickoff.

It's still showing as Carroll on your team screen because it is still the first gameweek until midnight tonight.

The link above should explain captain/transfer deadlines from now on.

Captain Change cut off for gameweek 2: Saturday 27th August: 12.05

Unfortunately, it wasn't very clear that the first sky gameweek extended into 2 actual gameweeks and it is perfectly understandable why you are confused.

I believe sky gameweeks will be of one week duration from now on.

But remember that kick-off could be Tuesday or Wednesday, so you need to consider that teams playing midweek, as well as the following weekend, effectively have a double chance of double captaincy points, so the double gameweeks in Sky tend to differ from those in FPL.

can i fiddle around with the captain now this week? or am i just allowed to change it once?

Only one captain change allowed per gameweek, i'm afraid.

You can fiddle around with it as much as you like until a game kicks off for the gameweek. Which won't happen until Saturday. I think that is what you mean. You can change your mind until a ball is kicked.

Yep thats what i meant.

Cheers guys.
