KEVIN GAMEIROLorient to Newcastle THE INSIDER says: 2/5
JORDAN HENDERSONSunderland to LiverpoolTHE INSIDER says: 4/5
Sportsmail revealed back in February that English clubs were very keen on the France international aware that he was ready to leave Lorient this summer.
Arsenal were the frontrunners but Lorient's demands for ?17m put them off. Since then Tottenham, Sunderland and Newcastle have all had close looks at the 24-year-old but only Alan Pardew has put forward concrete offers.
Sportsmail revealed that an ?8million bid had been rejected and they have followed that up with an offer for ?10m but the problem is that Gameiro wants to go to Spain with Valencia his favoured destination.
They have outlined personal terms with the player but have yet to match Newcastle's offer.
Paris St Germain have also entered the race and Gameiro would take that if only to play in the Champions League.
Newcastle retain hope but it looks to be fading and they may have to pin those hopes on persuading Lille's Gervinho instead.
The England Under 21 international has emerged over the past 18months to fanfares from the Stadium of Light and that has alerted Manchester City, Manchester United, Arsenal and Chelsea.
But it is Liverpool who have made the first strong move and that is his preferred destination. The key now is for the clubs to arrange a fee.
In PR terms the sale of Darren Bent did not do Sunderland any favours and they certainly can't be seen to lose face again over the sale of Henderson.
However, his form over the past few months would indicate a sale at around ?15million would still represent good business and allow the club to carry on rebuilding without too much damage.
Liverpool want to bring in young players with good re-sale value and see Henderson as a player who can solve their wide right problem and supplement the midfield. A deal should be brokered in the coming weeks.
PABLO PIATTIAlmeria to WiganTHE INSIDER says: 2/5
TOMASZ KUSZCZAKManchester United to West BromTHE INSIDER says: 3/5
Roberto Martinez has been tracking Piatti all season and would love to bring him to Wigan. However, despite Almeria's relegation they still want too much money for Wigan's budget. They bought him in 2008 for ?6.5m and want to sell for around ?8.5m.
The 22-year-old Argentinian can play in various positions and is another creative force that could add a new dimension to Wigan's play despite the fact he is only small in stature at 5ft 4in.
Tottenham, Atletico Madrid, Sevilla, Espanyol and Villareal have all watched him while Udinese and Lille are also reportedly keen.
Wigan are mindful that bigger Premier League clubs will be looking to take advantage of their squad this summer with Charles N'Zogbia, James McCarthy, Hugo Rodallega and Maynor Figueroa among the most likely to attract offers.
It's important they have new players lined up before they are left with the tough job at the end of the window of attracting players and being asked exorbitant money.
The Poland international is eager to make a return to regular first team football and a move back to West Brom may be his best option.
His final league appearance for United at Blackburn did not do him many favours but there are still plenty of admirers in the Premier League. West Brom are one.
Manager Roy Hodgson had wanted Brad Friedel from Aston Villa but his decision to choose Tottenham has left them looking for another reasonably priced contender as confidence in Scott Carson dwindles.
United would sell Kuszczak for around ?3million once David de Gea's move is ratified from Atletico Madrid. Wigan are also interested as they struggle to strike a deal with Bolton for Ali Al-Habsi but another consideration for Kuszczak is that he could take a chance and stay at Old Trafford in the hope that de Gea takes time to bed in.
Albion will be hoping he chooses them and that they can start building a more solid defence for next season.
