Viktor Gyokeres' decision to go on strike at Sporting has highlighted a major transfer concern ahead of a potential Premier League switch to Manchester United or Arsenal. The 27-year-old Swedish international has been heavily linked with a move away from Sporting after another impressive season in the Portuguese top flight.

Manchester United and Arsenal are both in the hunt for Viktor Gyokeres, but it now looks like former club Coventry City will not earn anything from a sale despite previously agreeing a sell-on clause

A Bola also claim Arsenal are ‘in a hurry’ to conclude the deal with Gyokeres also keen on the move to north London. Arsenal must now agree a fee with Sporting with club president Frederico Varandas yesterday accusing Gyokeres’ agent of trying to ‘threaten and blackmail’ the Portuguese champions.
