Sorry mate but as we said in France, we are not going to play "who has the bigger d...". It's been 32 seasons I play this game, I have won 28 leagues, 14 CL, as many cups and 7 trebles. And you know what ? I am wrong sometimes too. But if you read carefully the tactics part of this forum, you will see loads of posts about the weaknesses of 4-5-1V. Which is my main tactic. So my opinion is based on experience, wins and losses.
