If I remember correctly he kept his GS on strong and sometimes proficient but I did not follow all his weeks,so I think the training compensates the lost os shape from the 80 or more minutes and gives an up though it maybe little
but one thing is to train one week other is to train the entire season,but for decisive matches I think its valid
I would want confirmation by people that trained one week only,but the problem is the random factor so its always a tough decision
good luck either way,hope i helped,sorry about my english
