In the last six months or so, it has been abundantly clear that Theo Walcott's time at Arsenal is at an end.The Englishman did score 19 goals in all competitions last season, but the addition of Alexandre Lacazette and some sub-standard performances have seen him fly down the pecking order.A £20m move to Everton should be confirmed shortly, with Arsenal's fan base seemingly split on how to remember one of their most loyal servants.Let's not forget, Walcott signed a new long-term deal back in 2013 when he could have easily jumped ship to Chelsea when he was in the form of his career and still only 23.Throughout his Arsenal stint, Walcott has also been involved in 108 Premier League goals (65 goals, 43 assists) the fifth highest of any player under Arsene Wenger.So, was he really the disastrous flop that many portray him as? Perhaps not and one Arsenal fan on Twitter has made a fitting tribute to him by highlighting one crucial thing he gave the Gunners; an impact in big games.It's easy to forget how many times down the years he's been decisive when Wenger has needed him most.

Not a bad highlight reel and that's just against the big teams.

The same Twitter user also made a great point about how Arsenal fans view Walcott and Tomas Rosicky.

He could be on to something here.

One other Arsenal fan left another important message on the video, reminding people that Walcott still managed to return from a serious ACL injury and score some crucial goals.

Former Chelsea man Tony Cascarino believes that Walcott should be worth 'double' the £20m fee Everton are paying for him.

He said: “At £20million the Everton manager will think he has a bargain — in the form of last season Walcott would be worth double that.

“All forward lines are mobile now and Walcott could be deadly as part of a front three at Everton, playing on the shoulder of defenders, interchanging positions with Cenk Tosun and Yannick Bolasie.

“Don’t be surprised if he shows Wenger what could have been."
