why sell tomasson?

i was wondering... why is everyone convinced that tomasson is leaving?? .. and even if why do u want him to ... and not inzaghi??? ... personally i think selling inzaghi would turn out better for us... i think hes very overrated while the football world seem to disagree with me on that, on the market hes around saaaaayy.. 15M, JDT on the other hand is around 12M.. yet if u think of it, with gila coming who would u rather have as 3rd choice??? a nagging inzaghi or a JDT who would instead want to fight for a starting spot?? ... look at it age wise??? i personally dont care less about age but u gotta admit inzaghi is losing it while tomasson was in his prime last season (this season he was injured alot yet he still managed to score)... other than that, inzaghis comeback seems unreachable because of injuries, tomasson is much more fit..
