Everton striker Wayne Rooney is reportedly in advanced talks to join Major League Soccer side D.C. United this summer.

The 32-year-old is said to have become frustrated at Goodison Park and negotiations have "accelerated in recent weeks," according to Steven Goff at the Washington Post.

Everton manager Sam Allardyce said Tuesday he wants Rooney to stay and that it would take a "massive" offer to tempt him away from his boyhood club, per David Prentice at the Liverpool Echo:

"There are rumours about Wayne going elsewhere abroad – in China and America – but rumours are rumours we won’t find out until Wayne and his agent have been contacted whether he wants to move, but at the moment he is an Everton fan and an Everton player. So I wouldn’t consider anything on the cards on the moment. It would have to be massive for him to want to leave Everton. Do I want him to stay? Yes."

Rooney is Everton's top scorer this season with 11 goals in 36 appearances in all competitions for the Toffees. He also won the club's goal of the season award for his strike against West Ham United, as shown by the club's Twitter account:

The former England international only rejoined Everton from Manchester United in summer 2017, but it has been a difficult season for the Merseyside club. Manager Ronald Koeman was sacked in October 2017 after a poor start, and new boss Sam Allardyce has stabilised the club but is unpopular with supporters.

Everton fans showed their disapproval by walking out in protest at Allardyce at the end of Saturday's final home game of the season against Southampton, per David Maddock at the Mirror.

Rooney has defended his manager, per Indy Football:

Yet there has been friction between the striker and his manager. Rooney reacted angrily after being substituted in the Merseyside derby against Liverpool, per Telegraph Football:

Rooney has struggled for form in recent months and is yet to score in 2018. The striker is increasingly frustrated at Everton, and there are divisions at the club, per Dominic King for the Daily Mail.

The striker has also not quite had the impact at Everton that he might have envisaged when he returned, although he does still have another year left on his current contract.

Sports writer Thomas Floyd said he could have a big impact at D.C United:

Rooney may find himself increasingly sidelined next season if he stays at Everton, which could prove a factor in any decisions regarding his future. However, wrenching him away from his boyhood club could still prove to be a tough task.
