Should Glasgow Rangers keep their eyes on the progress being made by 22-year-old Sam Cosgrove, the tall centre forward of Aberdeen?
His contract with the Dons expires in May 2022, therefore he would cost the Gers a transfer fee if they wanted sign him and bring him to Ibrox next season.
Cosgrove has scored 20 goals in 47 games so far this season, excelling in a defensive Dons side. He has shown real potential to improve each year.
How many goals would he score in a very attacking Rangers side?
The striker would be playing with quality players surrounding and assisting him to score plenty of goals each season. Is he worth buying now, or just keep an eye on his progress?
In January 2018, striker Cosgrove joined the Dons on a free transfer, and he showed up well for Derek McInnes, who signed him an extended deal until May 2022.
Another Aberdeen player worth watching is centre-half Scott McKenna.
The 22-year-old centre-back is contracted to Aberdeen until May 2023 and as such would also cost Rangers a significant transfer fee to sign.
McKenna has shown that he has what it takes to excel in the Scottish top flight and his performances for Aberdeen have led to him being included in the national team set-up.
The Dons defender will surely be in demand this summer and it remains to be seen whether Rangers could stump up the required transfer fee to land the Scotland international.
A third Aberdeen player worth watching is goalkeeper Joe Lewis.
Rangers manager Steven Gerrard raved about the 31-year-old Dons keeper after a recent meeting between the sides, as the stopper pulled off two or three world-class saves.
If Rangers decide to sign Lewis, they would have to pay a transfer fee for his services, as his contract was recently extended to May 2023.
Dominic Ball of Rotherham United is available on a free transfer.
The 23-year-old is a versatile defender available on a free transfer as his current contract expires this summer.
Ball played at right back, left back, centre back and defensive midfield for Aberdeen whilst on a season-long loan deal from Rotherham.
The defender also played 30 games for Rangers on loan in the Championship in an on-loan deal from Tottenham Hotspur in 2015-16 – bringing him back to Ibrox could be an option.
