Blackburn Rovers will continue the push to bolster their squad with John Eustace keen to sign four more players before the transfer window ends.

Rovers have signed four players for the first-team squad this summer, plus agreeing to bring Kyle McFadzean back to the club on a new deal. However, there have been four exits too, with Leopold Wahlstedt, Semir Telalovic and Sam Gallagher departing. Jake Garrett has also head out on loan.

It means Rovers still have work to do with just under three weeks of the window to go and more arrivals are expected at Ewood Park.

It was very evident where the holes in the squad are. One goalkeeper, one defender, one midfielder and six attackers made up the bench against Derby County on Friday night.

A senior goalkeeper to compete with Aynsley Pears has long been desired. Rovers missed out on Jeffrey de Lange last week and have looked at Dutch goalkeeper Joel Drummel.

They looked at Asmir Begovic earlier in the window and his collapsed move to Charlton Athletic raises questions about whether they could return to that deal. Though is conjecture on my part and not anything concrete.

Whilst the profile of goalkeeper scouted in June were of an older profile, the additions of McFadzean, Danny Batth and Andi Weimann may have opened up the possibility of a younger option. De Lange is 26, Dromell 27. That's a move away from the likes of Begovic or Tim Kurl, both way beyond their 30th birthday.

At full-back, Rovers are desperate for some cover. There is every possibility that one of, if not both, Leo Duru and Jake Batty could leave before the window shuts. That won't happen without an incoming though.

Left-back is thought to be the higher priority, if only one arrives. Joe Rankin-Costello, Hayden Carter and Lewis Travis have all started Championship games on the right and could feasibly cover in the absence of Callum Brittain. There is more concern about the suitability of the current options if Harry Pickering were to break down for a considerable period.

A central midfield is sought to replace Garrett. Eustace is keen to add a different dynamic to his existing options. The loan market could be the avenue Rovers strengthen that position to not block the road ahead for others.

Pace and speed, particularly on the left side, is being looked at too. In an ideal world, a versatile forward who could play across the front line would fit the profile. 

Those four areas are a minimum that Eustace wants to be addressed, notwithstanding any exits. The future of Sam Szmodics, in particular, is up in the air.

It felt inevitable 10 days ago that he'd be following his fellow Sam out of the door. Now, it feels like this could rumble on for the final weeks of the window.

A fee of £10million with various add-ons and bonuses was always likely to get the deal done. But Ipswich have haggled and played hardball. Considering they are down to 18 contracted senior outfield players a week before the season starts, you wonder if that will be enough to make them stump up.

"We're short on numbers going into the season there's no doubt about that," McKenna admitted after their 1-0 win over Nice at the weekend. A clear signal he wants reinforcements.

Szmodics has been reintegrated and Rovers remain in a strong negotiating position. But his goal-scoring return should detract from the fact if Ipswich do finally hit the fee, he will leave the club.

With the court case looming too, it will be an action-packed and pretty crucial end to the window.
