The Saints have struggled somewhat of late, slipping to 12th in the Premier League table following a run of five wins without victory and only two goals scored.
Their latest 2-0 defeat at home to Tottenham Hotspur displayed a key weakness, with the Saints lacking in creativity in the final third and short on options in wide areas.
With January just around the corner, a new addition or two would be welcomed at St. Mary’s and reports suggest that Koeman could find an answer to his side’s problem in the Championship.
“The Saints’ manager is weighing up a January move for the 19-year-old Blues wing star and dispatched Erwin, assistant head coach at St Mary’s, to provide an assessment,” the Mirror report.
Demarai Gray is one of the Championship’s outstanding talents, breaking through into the Blues team last season and showing real promise at St. Andrews.
The England U20 international has started 21 Championship matches this season, averaging an impressive 2.9 shots, two successful take-ons and 1.3 key passes per match.
Gray is still very raw in terms of end product and decision making in the final third, yet his natural ability is evident and he has bags of potential – drawing comparisons with Wilfried Zaha.
As per the report in the Mirror, Bournemouth have already had a £5 million bid rejected for Gray and Southampton will know they aren’t the only club monitoring his progress ahead of January.
