I don't know how any professional footballer can 'deceive' others with their performances. At most they could maybe they can deceive a bunch of fickle Facebook fanboys whom rely purely on stats to evaluate a player, but coaches and fans who actually watch the matches cannot be fooled, of course a lot of it subjective, but there is usually a general consensus. There are many reasons for weight gain and lack of conditioning, again it's not black and white and player following the strictest of diets and most intense regimes can still find themselves out of shape due to their genetics or hormonal imbalance.
Suarez's performances speak for themselves, but he somehow isn't frauding his way into the lineup with his performances, but rather Valverde can see that he is off form but continues to start him because his pedigree and lack of proven options on the bench. I have no idea how you're equating my comments about Suarez to that of calling him a fraud.
You're grasping at straws here.
