I think the results under Puel will get better as the season winds down to it's conclusion over the next three months. The signing of Gabbiadini will be cited as the most significant factor (not unreasonably) but the decision not play a consistent starting 11 should not be overlooked. Today we played the same starting 11 as on Sunday. I didn't realise that Jake Stephens has now started 7 consecutive games which is the current record for our outfield players this season. The rotation was necessary but not to the extent that it was employed prior to Christmas.
FLT's comment about Puel's learning ability is too generalised. I would suggest that the formation and tactics used during the initial 4-5 months have been , to a degree, jettisoned. We are now playing at a faster pace than before and starting to do some damage when we break. This was not happening before Christmas where the number of attempts / goals ration was very poor. Granted that Puel has had experience at high level in French football , the Premier League is different and I still think that he took a far longer time to come to terms with this that either Koeman or Pochettino who were similarly untested. Talk of the use of a diamond and rotation will probably be a distant memory next season and if we continue to score the volume of goals as has been the case in t eh last few games, I will have not complaints. However, I stick by my assertion that whatever mantra Puel had prior to Christmas, this has now been abandoned and his teams are now more recognisable at Southampton sides.
