It's a common misconception that increase in size = increase in strength. It's not necessarily the case. Hence why you find professional bodybuilders twice the size of Olympic weightlifters, but who can lift significantly less. So, if certain players appear slimmer, they may not necessarily have lost muscular strength. Two types of muscle hypertrophy (growth): i) Sarcoplasmic (increase in cell fluid), ii) Myofibrillar (increase in myofibrils*). Sarcoplasmic hypertrophy will result in overall muscle size increase, but not an equal increase in strength. So, relating this back to the squad - the latter (myofibrillar hypertrophy) suits the training objectives of the squad more than the former, as we're looking for increases in strength, endurance, skill and speed. However, there clearly needs to be a base level of bulk in order to be effective (as you can only be so strong with a limited muscle size) - combining strength with a bit of bulk - which is needed to force players off the ball etc. I think certain players lack the required level of bulk which is needed to be most effective, e.g. Lucas, Benayoun, Skrtel, Agger, Arbeloa. However, I don't see the aforementioned players bulking up greatly as I think Rafa, and the fitness trainers, see increases in strength endurance, stamina, speed as more important training objectives. So, to sum up - Whilst a set level of bulk is needed, and a level of strength in order to 'guide' the bulk - it is because training to bulk up works against the most important training objectives, that makes it very difficult to get the correct balance.
I think it's safe to assume that the conditioning of the squad is being monitored quite closely - the club doctor intimated as much in an interview recently. The fitness trainers will be aware who's lost weight, who's gained weight, who's stayed the same. I think they'll also have done tests to assess the strength of the players. It simply depends on the objectives of the coaching team.
