#1 It is difficult to see what he is bringing to the table at Juventus
In football just like in life in general, every purchase is made to fulfill an underlying need or satisfy a want. When a transfer is made in football, it is mostly for one of two reasons: either to strengthen the first team or to act as an effective backup.
Paul Pogba is too high profile to be signed as a backup, but it is hard to see what he is bringing to the table as a starter at Juventus. The club's total dominance of the Italian game means that with or without Pogba, they would triumph domestically and it is a long sought after European crown which they seek.
Can Pogba be trusted as the man to take them all the way to European glory? On the evidence of his sojourn at Manchester United, that answer would have to be no, as he showed a penchant for going missing when it mattered most and his seeming nonchalance and indifference to football-related matters means he is always a ticking time bomb waiting to explode.
The Juventus midfield was criticized for not scoring enough goals last season and while Pogba would help a little in this regard, it is rather ludicrous to suggest that he would bring the solution to their goalscoring midfield woes.
At best he is a little less than average goalscorer and while he might be coming off the best goalscoring returns in a season of his career, 16 goals in all competitions is not really earth-shattering stuff.
In 95 Premier League matches for Manchester United in the last three seasons, Pogba scored just 24 goals and this figure becomes even less impressive when you consider the fact that seven of those were penalties.
During his first spell at Juventus, Pogba was supported by Andrea Pirlo and Arturo Vidal in midfield, with the Italian providing the guile while the Chilean provided the grit, giving Pogba the license to roam forward on the left hand of a midfield three.
As stated earlier, Sarri's tactical demands mean that such a scenario is unlikely to play out and with his on-field importance being questioned, it is hard to see where else his value lies.
Paul Pogba is undoubtedly one of the most marketable players in the world today and would give any club a marketing boost, but €150m for a transfer plus one-fifth of that in salary outlays is a tad too much for a player who would only be bringing commercial value.
Moreover, Juventus already made their statement signing when they brought in arguably the most marketable player of all time in Cristiano Ronaldo last summer and at least the Portuguese has a track record of being a proven performer of the optimum level.
Pogba's signing at best would be a luxury one with minimum importance on the field and with funds needed for transfers elsewhere, it is imperative that Juventus steers clear of signing him.
