Chelsea's Champions League!

In my 5th season of football manager with Chelsea having won Premier League in my first season, and 3 champions leagues consecutively the next three years (as well as fa cups and carling cups). Admittedly, I struggled in the league during those seasons, finishing 2nd, 3rd and 4th, but more than once, I was drawn against Barcelona and AC Milan during the CL triumphs. Attacking 4-2-3-1 formations did wonders at home against both, whilst playing a balanced, standard tactic earned a victories at camp nou! In the league, I haven't changed my main formation in any season, which may not be great, but a 4-2-4 with 2 wide attacking midfielders (Mata and Afellay), with Torres and Doumbia/Drogba up front won the league. Lukaku was shipped out on loan for 2 seasons and now in my 5th season averages a goal a game, as do torres (now 31) and Jovetic.
New signings have been made of course, notably Pastore, bought for a bargain of £15 million, at 4 stars, Jovetic at a pricely £37.5 million pounds, also 4 stars, Christian Erikson who has been outstanding in central midfield alongside Ramires, and is also assist leader. Otamendi was signed for £13 million, another bargain considering his defensive attributes. Reminds me of Carvalho, not the strongest or biggest, but brilliant with his positioning and marking. Chygrynskyi was signed on a free and is a brilliant squad player, and Schennikov at left back as a replacement for Cole, though Bertrand has been better!

Would you mind putting screenshots of your formations and tactics please? Always struggle to get them right with Chelsea, and also how good is Mata for you? and where do you play him? (he always seems to be bad for me)

I play Mata in left attacking mid as a winger. His best position is trequartista in central attacking mid, apparantly, but he's always averaged over 7.00 for me and has been just as, if not more effective than his central position. I'll put screenshots up shortly

thanks
