Leeds United made their first pre-season signing this week.
New manager Garry Monk wrapped up Leeds' first signing of the summer by welcoming striker Marcus Antonsson to the club for £2 million this week, with defender Kyle Bartley - whom the young coach worked with at Swansea City - following on a season-long loan.
Considering they finished 13th in the Championship under Steve Evans - who only replaced Uwe Rosler in October and comfortably achieved his remit of keeping United in the division - last season, it would suggest that there's a bit of work to be done if the Whites want to win promotion back to the Premier League next term.
Leeds fans will be hoping that Antonsson and Bartley are the first signings of many, and Diagouraga agrees that wholesale reinforcements are needed if the Yorkshire side wants to reach its goals next season.
“If we are to achieve what we want to achieve, then we will have to improve everywhere," he told LUTV.
“I am sure the staff have been working behind the scenes to make that happen.”
At 38, Monk remains something of an unknown quantity in football management.
He lasted a little less than two years as Swansea City boss - his only other managerial role to date - and it is difficult to predict how he will fare at Elland Road, but signings are key.
