Swansea City kick-start their Championship campaign at Blackburn Rovers this weekend.
Russell Martin will have just five days on the training ground with his new squad after joining the club from MK Dons on Sunday evening.
Saturday's pre-season defeat to Southampton served as a timely reminder that Swansea's squad needs strengthening this month.
The club have already signed Kyle Joseph, Joel Piroe and Liam Walsh, although captain Matt Grimes and George Byers are both expected to leave.
Swansea played with a back four in defence throughout pre-season, although Martin deployed a back three during his time at MK Dons.

With Jay Fulton suspended and Connor Roberts unavailable due to injury this weekend, Swansea could well go with the same starting XI from Saturday's clash with Southampton at the Liberty Stadium when they travel to Blackburn - depending on the fitness of central midfielder Walsh who limped off with a minor hamstring issue.
Grimes - who missed the matches against Forest Green Rovers and the Saints - could yet be thrown into the limelight at Ewood Park, depending on his transfer situation along with the injury status of others.
However, should Martin persist with a back three in his new job, some significant tweaks will need to be made while additions would be required.
Jake Bidwell would shift to left wing-back, although one of Joel Latibeaudiere and Kyle Naughton would need to move to right wing-back. The other would slot into the back three along with Ryan Bennett and Ben Cabango.
A 3-4-3 would afford Swansea the opportunity to stick with three up top which would see Piroe, Liam Cullen and Morgan Whittaker slug it out for the two spots alongside Jamal Lowe. Yan Dhanda would be the most likely fall guy here as Walsh and Korey Smith could start in midfield.
But you'd suspect Swansea really need to bring in an additional central defender if they are to play a 3-5-2 or a variation of that shape this season.
They had been keen to sign Jimmy Dunne, although after failing to agree a compensation fee with Burnley, the Republic of Ireland Under-21 international joined Queens Park Rangers.
The Swans have their full quota of loan slots to fill, and at least one of those will need to be used on a creative player while a few more goals in the squad wouldn't go amiss.
As far Saturday though, once the formation is clear, the team practically picks itself. A clean slate could be just what players like Dhanda, Whittaker and Latibeaudiere crave.
But it's fair to say plenty of questions will be answered between 3pm and around 4:50pm on Saturday as the Swans begin what is their fourth successive season in the Championship.
Possible Swansea lineups at Blackburn
4-3-3: Benda; Naughton, Cabango, Bennett (C), Bidwell; Walsh, Smith, Dhanda; Lowe, Cullen, Whittaker.
3-4-3: Benda; Cabango, Bennett (C), Naughton; Latibeaudiere, Walsh, Smith, Bidwell; Whittaker, Cullen, Lowe.
