[Getty Images]After another defeat at Wrexham, Mark Robins set out exactly what he wants from the summer transfer window and players who come in will need to have the physicality and reliability to compete in the Championship over a full season.He said he, the club's ownership and recruitment team have a lot of work to do to create a squad full of players with those characteristics, in addition to the quality required to improve on a season during which they've struggled in front of goal.Stoke finished the game with two wingers at full-back and an attacking full-back at centre-half, partnered by an 18-year-old making his professional debut.They also finished the game with more injuries to defenders to contend with at the end of a season defined by injuries to key players all over the pitch.Wrexham scored two goals in two minutes, one straight from a corner and one after a mistake from Aaron Cresswell.Both goals were poor from a Stoke perspective but the Potters had chances of their own and plenty of the game.In the end, poor decision-making or execution in the final third, and an inability to match Wrexham's strength, dismissed any hopes of a comeback.Those are the themes of the season and exactly the issues that will need resolving over the summer.
