Aston Villa boss Paul Lambert says striker Darren Bent is not for sale ahead of the close of the transfer window.
It is understood Saphir Taider is set to leave Southampton just three weeks after arriving on a season-long loan.
AZ Alkmaar have confirmed the shock departure of coach Gertjan Verbeek - just a day after he guided the club to victory over Eredivisie leaders PSV Eindhoven.
In a statement, the AZ board pointed to a "lack of chemistry" between the coach and his squad as the reason for his sudden exit.
AZ sit fourth in the league standings in the wake of Saturday's 2-1 win over PSV and are contesting the group stages of the Europa League, with a game to come against PAOK on Thursday.
"Coach Gertjan Verbeek leaves AZ with immediate effect," read a statement on club website az.nl.
"Based on a lack of chemistry between players and the head coach resulting in a lack of confidence, the management and supervisory board sees no more basis for further co-operation."
The 51-year-old joined AZ in 2010 and signed a contract extension through to 2015 just last summer.
He has secured European qualification in each of his three full seasons at the club - twice after finishing in fourth place in the league and again by winning the KNVB Beker last season.
The club statement did not announce who would replace Verbeek, but a press conference this afternoon is expected to shed further light on the surprise development.
