Wigan boss Paul Jewell has confirmed the Latics have made a bid for Birmingham striker Emile Heskey.
Jewell also admitted making enquiries about Robbie Savage to Blackburn who indicated he was not for sale.
'Emile is a proven performer at Premiership and international level and we have made what we consider to be a very good offer to Birmingham City,' Jewell told the club's website.
Jewell is desperate to land a quality striker, especially after seeing Jason Roberts join Blackburn for £3million last week.
However, the Latics boss has again struggled to attract quality names to the JJB Stadium this summer, notably failing with an £8.5million bid for Andy Johnson, with the striker opting for Everton.
Although Heskey's goalscoring record with Birmingham is unimpressive - just 16 in 78 appearances - Jewell sees the 28-year-old as an ideal signing.
'It is not normal for this club to comment on targets until the player has signed,' added Jewell. 'But in this instance it's an open secret that we've made the bid.
'I think he's a player who could do very well for us, but we'll see how the situation develops.'
Birmingham, meanwhile, are poised to sign defender Bruno N'Gotty on a free transfer.
The French centre-back, 35, was out of contract with Bolton and is set to join Steve Bruce's side as they look to make an instant return to the Barclays Premiership, with the final details of the move expected to be completed shortly.
Blues have signed striker Cameron Jerome, midfielder Neil Danns and full-back Stephen Kelly since they were relegated from the top flight.
The fact Jewell was chasing Savage had also been speculated upon over the past week, but again Wigan were rebuffed.
'We did ask Blackburn about Robbie through the correct channels because he's a player I thought would be a good addition to our squad,' stated Jewell.
'But Blackburn said he was not for sale. That's as far as the conversation went. We never spoke to the player, we didn't make him a wage offer and as far as I'm concerned the matter's closed.
'We move onto other targets. But it shows the ambition of the club that we are now targeting some of the Premiership's top performers.
'I'm still very confident we will get the five or six new players we want by the beginning of the season.'
Former Wales international midfielder Savage has also indicated he has no intention of leaving Ewood Park.
Despite Craig Bellamy quitting Blackburn for Liverpool for £6.5million earlier this summer, the 31-year-old will not be following his close friend out of the club.
'I am more than happy at Blackburn,' insisted Savage. 'I knew when I left Birmingham this was the right club for me and nothing has changed.
'It was very flattering for me they showed an interest, but there's a UEFA Cup season ahead and I'm very much looking forward to it.'
