Manchester United and Chelsea must move swiftly, if they want to grab Griezmann

The French striker is attracting plenty of interest, but Atletico Madrid aren't willing to let him go without a fight.

Twenty goals in 31 La Liga appearances, with six of those in his last four outings, when it comes to the future of Antoine Griezmann, it's easy to see why tongues are wagging. In such eye-catching form, recent reports have linked the 24-year-old with interest from the Premier league.

Earlier this week, The Express pointed towards Jose Mourinho and Chelsea weighing up a summer move. Meanwhile, The Telegraph hinted that Louis van Gaal and Manchester United, may also make an approach.

Although they were unable to prevent Diego Costa leaving for Stamford Bridge last summer, when it comes to Antoine Griezmann, a much tougher fight can be expected from Atletico Madrid this time around.

Having successfully made the transition from being more of a wide player, to a central striker, Griezmann has thoroughly earned the respect and praise of his manager, Diego Simeone. He certainly won't want to see such a talent leave.

Atletico splashed out €30 million to secure the signing of Griezmann from Real Sociedad last summer, but somewhat surprisingly, his current release clause only stands at €35 million.

That's something the hierarchy at the Vicente Calderon are very keen to rectify, otherwise, they could find themselves losing another of their key players.

In the Spanish capital, it is believed Atletico plan to sit down with Griezmann and his agents at the end of the season. Negotiations will involve an improved salary package and terms, but most importantly for the club, raising his release clause valuation to €60 million or more.

Manchester United and Chelsea will likely want to maintain good relations with Atletico Madrid, given the business between the clubs in the past. However, if their interest is genuine, they might have to take a tougher approach.

Lodging an official bid matching the current release clause, would force Atletico Madrid to the negotiating table, leaving the final decision down to the player himself. Given the interest of Bayern Munich, as highlighted by Sport Bild in Germany, there's also another important rival for the two English sides to consider.

Both Manchester United and Chelsea have also been linked with Palermo's Paulo Dybala, but his valuation seems to grow with each passing day. €50 million the latest price tag, hung around the neck of the sought after Argentine starlet.

By comparison, Griezmann has more of a track record, both with Real Sociedad and Atletico Madrid, having played in the Champions League for the last two consecutive seasons, whilst his goals tally in La Liga has also increased year on year. He's already proven his worth.

At a fixed price of €35 million, a move for the talented Frenchman would represent a sound piece of business, for either Manchester United or Chelsea. They have a window of opportunity before that valuation doubles, and they shouldn't let that opportunity go.
