this tactic is really good!
have used in the second season of Dinamo Zagreb and managed to win Europa League, with some key signings of course...
personally, i think the "control" tactic is better, players do not tire that much and defensively it's much more solid, also player ratings are 99% of the time at first five minutes of every match around 6.8 or 6.9 for everyone, and gradually go higher...
i have lost with the control tactic of course, especially in european matches, but managed to crawl back in second leg matches... overload tactic is also good, but now i use it only to catch up result, but i think it is too risky anyways...
think the key to this tactic being rock solid is good team talk and high condition of players, if they go into the match prepared and motivated they will not slip in the first 15min and get beaten by benfica 4:0 in champs league (H)(H)(H)
in the domestic league cup i have won almost every game, someting like a couple of draws and one lost in the cup semifinal 1:0 against Hajduk.
also - i think it works rather well when instead of two MC's you use ML and MR, at least one of those position instead of MC's, when you ran out of MC in the squad... the tactic works well that way too..
