Weighing it up I think I'm going to play the wildcard this week. I'm backed into a corner after a bad first week, don't have Haaland in my team when he has amazing fixtures incoming, have Son up against Chelsea, have Dalot and Sancho who I don't fancy at all against Brentford and then they have Liverpool the week after. Ward and Raya in goal too who don't have great fixtures in week two.
I think I'm leaning towards playing it too because once I play it most of the core of my main team won't need taking out before the world cup when we get unlimited changes anyway. TAA, Robertson, Haaland, Cancelo and Salah will likely stay in my team the entire time unless something crazy happens, you fancy them all in almost every fixture apart from maybe the Liverpool defenders when they play City but that's one game. Any of the surrounding players can easily be changed with the free weekly transfer when needed. I get the idea of having the wildcard in your back pocket and if you had a great first week then you don't really need to use it but I feel after a piss poor first week it's forced my hand and it seems pointless waiting 4-5 weeks to play it when I feel it will be more effective now than in a month or so.
