Conceding loads early against big teams

This almost always happens to me when I'm playing a big team, and NEVER when I'm playing a smaller team. They score about three goals in the first ten minutes, and then score none in the second half.

For example, I was playing Juve with AC Milan, I conceded 5 in the first half, but then won the second half 2-1. Final score was 6-2 obviously.

Why does this keep happening when I play big teams, because against small teams it never happens. Is it a tactical issue or something else (I don't think it is tactical as this has happened with many different tactics)?

I think it's probably tactical.

Of course it won't happen playing a smaller team. They don't have enough skill to score 5 goals at AC Milan. I think that what's probably happening is that you're too offensive (or maybe your tactic is just too inadequate to the match). They score too much at the beggining and then stop, but that's just normal. Teams tend to get accommodated after they build a good lead.

Try starting with counter as your mentality, I've found it working quite well against bigger sides. Retain possession and hassle opponents often help (although hassle can be counter productive as intelligent opponents will exploit the gaps)

Hope this helps

I'd also use "pass into feet" to reduce through balls and hopefully cut down the number of intercepted passes, "play through defense" is a similar shout, cutting down running with the ball and through balls. Unless you have great passing players in your defense "play out of defense" is a great shout that makes your defenders with a defensive mentality (CB's really) play shorter passes rather than lumping it forward.

"Hassle opponents" can be a useful shout as it raises the tempo, tightens your marking and gets your players closing down more, as Kez said this can open gaps against better players so it's sometimes better to use "stand off opponents" which keeps marking loose and zonal but also means your team keep their shape and don't go charging after their markers. If your Asst mentions "player X is getting skinned..." It's a good idea to switch to "stand off..." for a while.
