Gabby Agbonlahor fears Aston Villa have a serious Ezri Konsa conundrum on their hands and it may end in a summer sale.Speaking on talkSPORT Drive, Agbonlahor outlined Konsa has two years left to run on his current deal with Villa.Konsa’s future has been called into questionGettyHowever, should he look to sign a new contract, Konsa may demand wages on a similar level to his World Cup centre-back partner Marc Guehi, who talkSPORT understands to be earning around £300,000-per-week.If Konsa is to make such a request, Agbonlahor is worried it will force his beloved club to make a decision worth tens of millions.Gabby: Konsa is the one I ‘worry’ about“If you’re Konsa, you started at the World Cup, you’re England’s best defender at the World Cup,” said former Villa star Agbonlahor.“What do you reckon Guehi’s earning at Manchester City? £300k? Seems like the going price, doesn’t it, for Man City?“Aston Villa can’t pay that… he’s probably thinking, ‘I deserve that’ and I don’t think anyone at Aston Villa will say he doesn’t. He does but Aston Villa can’t pay that.“That’s the problem Aston Villa have got. Do they sell him this summer, or do they wait until next summer where you’re not going to get the £70-80 million? Whatever you want for him. It might be £40million, that’s the one I worry about.“It’s hard to keep hold of them when they’re starting for England. Look at Morgan Rogers, he’s playing for England.”Should Villa elect to cash in on Konsa, they stand to make a significant profit on the £12m they paid Brentford to sign the defender in July 2019.E-z does itThe 28-year-old has gone on to establish himself as one of Villa’s greatest defenders in the modern era, racking up over 280 appearances across all competitions for the club.In that time, Konsa has been involved with Villa avoiding relegation on the final day of the 2019/20 campaign, helping the club record two fourth-place finishes in three seasons and ending their 30-year wait for a major trophy courtesy of the Europa League.Konsa has become Villa’s Mr. Reliable at the backGettyKonsa’s composed displays for Villa helped establish him as an England international, featuring in all eight of the Three Lions’ fixtures at this year’s World Cup.It has been a busy summer already for Villa, who have experienced a string of high-profile outgoings.From Villan to villainMorgan Rogers became the most expensive British player in history when he joined Chelsea for £117m while Youri Tielemans moved to Manchester United after they triggered his £35m release clause.Left-back Lucas Digne also appears destined to join Paris Saint-Germain for less than £10m.Villa could ill-afford to lose Konsa this summer given his centre-back partner Pau Torres has already voiced his intention to leave the club on a free transfer in 2028.However, it hasn’t all been one-way traffic out the exit door of Villa Park this summer.Unai Emery has lost a number of key players this summerGettyThe club broke their transfer record to hijack Newcastle’s move for Swiss midfielder Johan Manzambi while Joao Gomes was plucked from West Midlands rival Wolves.Alejandro Garnacho also joined the Villans from Chelsea on a season-long loan, although the deal contains a conditional obligation to buy clause.
