[ad_pod ]According to South American journalist Cesar Luis Merlo on Twitter, Southampton are set to make an offer to Brazilian side Gremio for defender Walter Kannemann.

What's the deal, then?

It is being reported that the 28-year-old could be subject to a €12m bid from Saints and Premier League rivals Wolves, who are also said to be interested.

The centre-half has never played in Europe having moved from Argentinian side San Lorenzo to Mexican outfit Atlas, before joining Gremio.

He has made 86 appearances for his current club, contributing three goals and one assist, while he has five caps for Argentina.

Kannemann is all wrong for both Saints and Hasenhuttl

The manager at St Mary's, Ralph Hasenhuttl, has already made two signings this summer in the attacking department with Moussa Djenepo and Che Adams both joining the club for a combined total of £30m.

So, the south coast side have already spent a decent amount of money to improve the squad and as a result without selling anybody other signings could be considered a financial risk.

And a defender in his late 20s who is unproven in not only the Premier League but all of Europe is by no means a guaranteed success.

Also, Hasenhuttl said in an interview with German newspaper SportBild back in June that his transfer policy over the summer is to bring in players under the age of 24.

Djenepo and Adams both fit the mould of that policy, so signing the Brazilian defender would be a left-field acquisition given the strategy which has been set out by the Austrian.

Then there is also the fact that Gremio play with a four at the back and have done so for every game so far this season - the Brazilian league is only mid-way through.

Compare that with Saints' set-up last year - they lined up with three at the back for 15 of the 23 Premier League games which Hasenhuttl was in charge of - and that could be an issue, although the 51-year-old could still choose to return to the 4-2-2-2 system that served him so well at RB Leipzig next term.

It is clear he does not fit the mould age-wise or in terms of experience, and therefore those in charge at St Mary's should seriously consider looking elsewhere.
