Theo Walcott posted a Twitter message on Sunday morning that suggests he is starting for Arsenal in their lunchtime Premier League showdown against Tottenham.

Walcott has missed the last two Gunners matches with a hamstring injury but was pictured taking part in first-team training on Saturday.

He took to his personal Twitter account on Sunday morning to tell his 1.3million followers that he was “match ready”, alongside an image of him in his full Arsenal kit at the club’s training headquarters.

The rare post from Walcott hinted that he has been given the nod by Arsene Wenger to return to the starting XI against Arsenal’s bitter rivals.

The England international has been on fire this season, scoring eight goals from 11 matches in all competitions.

Wenger is expected to make up to five changes to the Arsenal team that beat Champions League minnows Ludogorets 3-2 on Tuesday evening.

It is likely that the Gunners manager will rejig his starting XI as he picks the strongest possible side.

Walcott, Petr Cech, Nacho Monreal, Hector Bellerin and Alex Iwobi are all in line for recalls, with David Ospina, Kieran Gibbs, Carl Jenkinson, Aaron Ramsey and Olivier Giroud set to drop to the bench.

Leading scorer Alexis Sanchez is expected to spearhead the attack, with Giroud dropping out of the starting eleven.

The France striker has scored three goals in his last two appearances for the Gunners, but Wenger is expected to choose the more dynamic Sanchez against the Premier League’s tightest defence.

With Sanchez moving to the striker role it is likely that young star Alex Iwobi will return into the left side of the attacking midfield three given his impressive start to the season.

Behind them will be central midfield pair Francis Coquelin and Granit Xhaka, who is expected to get the nod to start ahead of Mohamed Elneny and fit-again Ramsey. Santi Cazorla was once again absent from training on Saturday and is expected to miss out once again with an achilles injury.

In other Arsenal team news, defender Per Mertesacker has revealed that games like Tuesday night’s win against Ludogorets is his motivation to return to full fitness.
