Despite this, Danny Cowley has a clear idea what attributes he wants from the four forwards he desperately wants this summer.
As a result, we’ve examined the stats from last season to see which front men would be the perfect fit for the Blues.
But who are they?
Here’s who we’ve selected from with the help of Wyscout’s statistics
1. Scott Kashket – Crewe
Although he scored only once last season, wyscout has Kashket down as one of the quickest players in League One last season. Perhaps he struggled in a team fighting for safety and Pompey could unearth a hidden talent. Picture: Naomi Baker/Getty Images Photo: Naomi Baker
2. Alfie May – Cheltenham
Although May's 28, he still has plenty of years in him to score goals. Last season, he scored 26 times in 53 appearances and proved himself as one of the classiest front men in the League One for the Robins. Picture: Pete Norton/Getty Images Photo: Pete Norton
3. Kyle Hudlin – Solihull Moors
It's clear to see the category Hudlin fits into due to his height of 6ft9in. Despite his towering presence he's still mobile enough and has one of the highest dribbles completion rate in the National League. Last term he scored five goals -- including in the National League play-off final. Picture: Alex Livesey/Getty Images Photo: Alex Livesey
4. Macauley Bonne – QPR
Cowley is no stranger to Bonne and wyscout has him down has one of the smoothest operators in League One last season. For Ipswich he scored 12 goals and could be deemed surplus to requirements again at Loftus Road. Picture: Alex Livesey/Getty Images Photo: Alex Livesey
