Real Madrid have announced an agreement to sign highly-rated teenage defender Jesus Vallejo from Real Zaragoza.
Aston Villa have continued their spending spree after securing the services of Rudy Gestede from Blackburn on a five-year contract.
Wigan boss Roberto Martinez would be flattered by speculation linking himself and some of his players to other clubs - if he was taking any notice.
Earlier this month the Spaniard rubbished claims he was set to quit the club this summer while fresh reports this week have linked him with Greek giants Olympiacos.
The futures of players such as Hugo Rodallega, James McCarthy and Victor Moses have also been the subject of conjecture throughout the season.
But Martinez, who last summer resisted overtures from Aston Villa to stay at the DW Stadium, is paying no attention and focusing only on his side's battle against relegation.
The 38-year-old said: "I have got no time to think about that.
"Those stories are there - so be it - but I don't think we have to talk about them.
"With all these stories - as I always said with players - if you get attention from other clubs it must be because we are doing something right.
"We should all be pleased, but we will never lose concentration on the job in hand.
"What we have got on our hands is one of the biggest moments in the club's history.
"Any story that is away from that - it is not the time and it is not important."
Wigan, having spent most of the season in the Barclays Premier League bottom three, were being widely written off in the relegation scrap just over a month ago.
Since then a series of remarkable results, including wins over Liverpool, Manchester United and Arsenal, has lifted them out of the drop zone and within reach of safety.
But defeat at Fulham last weekend still leaves little room for error and Martinez wants no distractions ahead of Saturday's visit from Champions League-chasing Newcastle.
He said: "I am extremely proud of the team and the results we have been getting.
"But we have done nothing, we need to concentrate on the next three games.
"That is not just for myself but for everyone - the staff, players and everyone connected to the football club.
"All we are talking about is Newcastle and making sure we are as good as we can be in the next three games, and nothing else."
Wigan, who beat the drop on the final day of last season, are just a point above 18th-placed neighbours Bolton, who have a game in hand.
After the Newcastle test, Wigan wrap up their campaign with games against fellow battlers Blackburn and doomed Wolves and Martinez envisages more twists and turns ahead.
Martinez said: "I am not looking at the table at all.
"We are fighting to get points we lost really early in the season but since February we have found a very good level of performance and that is all I am concentrating on.
"Carrying on that level until the final moment of the final game is all we want to do.
"If we do that then we can look at the points tally and see where it takes us.
"It would be a big mistake now to think we are safe just because we are outside the relegation places."
Martinez is hopeful Rodallega will have a role to play in the season's closing fixtures as he nears full fitness.
The Colombian striker, scorer of the vital late winner on the final day against Stoke last season, has been out for seven weeks with a knee problem but is now back in training.
Martinez said: "We will assess him over the next two days but he is slowly getting ready to make the squad, which is great news.
"Hugo has got something quite special - he has been able to grab the big moments and score goals.
"We all saw what happened last season and that is something natural. I don't think you can coach that to anyone.
"To have that in the squad is of real value and all we want is everyone in the squad to be fit and available to help the team in the last three games.
"There are going to be big moments, big emotions and we need every player ready to perform. Hugo is no exception."
Fellow forward Franco di Santo is doubtful with a calf problem while defender Ronnie Stam is unlikely to feature after suffering a hamstring injury in training.
