Aberdeen are closing in on signing a second Republic of Ireland midfield star this summer.
The Reds aim to secure four-time capped international Stephen Gleeson, 29, who is a free agent having left Ipswich Town.
Aberdeen have already secured Republic of Ireland squad midfielder Chris Forrester, 25, on a three-year deal from League One Peterborough United.
Gleeson earned his first two caps in 2007 and had to wait a decade to represent his country again last year.
He netted when coming off the bench in a 3-1 defeat to Mexico last June.
Forrester and Gleeson are both from Dublin and the Reds will jet off to the Republic of Ireland at the end of this month for a training camp where they will play Cobh Ramblers on June 30.
McInnes is keen to add to his squad before returning for pre-season on Friday June 22 but has missed out on Ross County right-back Jason Naismith.
The Reds are understood to have made a player plus cash offer for the 23-year-old.
However, Naismith has signed on at Peterborough on a three-year deal for a fee understood to be £250,000.
Former Scotland U21 international Naismith had two years remaining on his contract at relegated Ross County.
League One Sunderland, now managed by former St Mirren boss Jack Ross, also pitched in with a £200,000 bid for the highly-rated full-back.
One of the factors in Aberdeen losing out on Naismith was the full-back’s desire to experience action in England.
Naismith said: “It has been a stressful couple of weeks for me and I am delighted to join the club and want to kick on.
“I had played in Scotland for a couple of years now and coming down here (England) was big in my thoughts.
“A few boys have come down from Scotland and have done well and I hope to follow in their footsteps and help the club achieve something this season.
“Ross County are a great club but this is the right move for me at the right time in my career.
“There are big clubs in League One although we have big clubs in the Premiership in Scotland, but the pull was to come and test myself in a different environment.
“Now I can concentrate on my future, get my head down and work hard.”
Peterborough assistant Paul Raynor was delighted to beat the Dons and Sunderland to sign Naismith.
Raynor said: “He is a much sought after player. Everyone can see that with the calibre of clubs who have been interested.
“We are delighted.”
Dons boss McInnes will have to restructure his squad during the summer having lost 10 players, permanent and loan signings, at the end of the season.
He has already secured Hamilton’s teenage midfielder Lewis Ferguson.
McInnes is keen on signing striker Kenny Miller who is a free agent having left Rangers at the end of the season.
The 38-year-old is also being tracked by his former club Hibs, St Mirren, Motherwell and Dundee.
Premiership new-boys Livingston are keen on securing Miller in a player-manager role.
Dons boss McInnes met with the striker recently in Florida.
Aberdeen will discover before they return for pre-season training at the end of next week if their bid to secure Miller has been successful.
Miller is set to have talks with his agent this week and has confirmed he will make a decision on his future soon.
