Sheffield Wednesday chairman Milan Mandaric says he is eyeing around four new signings to bring in to Hillsborough this summer, providing some existing contracts are renewed.
The Championship side are looking to tie up the contracts of a number of current players, with Miguel Llera, Jermaine Johnson, Giles Coke, David Prutton and Stephen Bywater all being offered extended deals ahead of the new campaign.
Owls manager Dave Jones guided his side to an 18th place finish last season in their return to the second tier, and Mandaric says he is now looking to help them progress further by bolstering the squad.
"I'm looking at around four players. It could be more. It depends on how many of our existing players renew their contracts," he told the Sheffield Star.
Striker Chris O'Grady has been linked with a return to Yorkshire rivals Barnsley, where he spent the second half of last season on loan, and Mandaric hopes his future can be decided soon.
He added: "Barnsley need to make a decision quickly because we need to start to plan our season."
Robinson made 38 appearances last season, scoring 10 goals, and the 33-year-old was named League One player of the month for August after scoring a hat-trick at Carlisle.
After starting his professional career with Rovers, he played for Swansea and Leeds before returning to Prenton Park permanently in 2011.
"Andy has been one of the first names on the team sheet since I returned to the club and I'm delighted he will be staying with us," said Tranmere manager Ronnie Moore.
"He's a great creative player with vision and awareness and as well as scoring goals he creates chances for his team-mates.
"There are not as many vocal players in the game as there used to be but Andy is a real presence on and off the pitch and someone who can help our younger players."
