Arsenal moved back into the top four of the Premier League courtesy of a 4-0 victory over struggling Swansea on Saturday.

The Gunners had dropped out of the Champions League places following a 3-3 draw with Bournemouth last time out, but goals from Olivier Giroud and Alexis Sanchez, alongside own goals from Jack Cork and Kyle Naughton, secured an easy win for Arsene Wenger’s side at the Liberty Stadium.

It means that the Gunners move above Pep Guardiola’s Manchester City into fourth after the latter’s 4-0 defeat at Everton on Sunday, although Wenger’s men remain eight points behind league leaders Chelsea after they beat Leicester 3-0 at the King Power Stadium.

Nonetheless, that 4-0 win was exactly what Arsenal needed after three games without a victory on the road, with the Bournemouth draw coming after defeats at Everton and Manchester City.

However, as well as a 2-1 victory over Preston in the FA Cup, the Gunners are beginning to hit their stride once again, and will head into Sunday’s game against Burnley confident of recording a 14th league victory of the campaign.

Yet, many still feel that Wenger needs to strengthen in January to sustain a title challenge in the second half of the season, which could mean that some of those on the fringes of the first team may be moved on this month.

Thus, here are TWO Arsenal stars who must leave the Emirates in January to better their careers…

Kieran Gibbs

Nacho Monreal appears to have usurped Kieran Gibbs in the left-back pecking order this season, and he doesn’t look like relinquishing his grip on that spot.

Although the Spanish international isn’t the quickest full-back or most talented, he works hard for the team and consistently defends well down the left-hand-side.

When he has had the odd off-day, Gibbs hasn’t always done enough to convince Wenger of his superior defensive abilities, and thus has been restricted to just two Premier League starts this season in comparison to Monreal’s 19.

Thus, the England international must be considering a move away from the Emirates in a bid to resurrect his career.

At 27 years of age, Gibbs should be entering his peak years and, if he still harbours ambitions of adding to his ten England caps, then he must move on this month.

He’d do a job at many a mid-table Premier League side, and a sustained run of first team action could be what he needs to get back to the heights of 2013 and 2014.

Alex Oxlade-Chamberlain

Despite having his best goal-scoring season to date at Arsenal this time around, Alex Oxlade-Chamberlain is still struggling to nail down a first team spot at the Emirates.

The England winger has scored six goals in 27 appearances for the Gunners this season, beating his previous best tally of four from the 2011/12 campaign, but over half of his appearances thus far have been from the bench, and he has completed 90 minutes just three times this season.

With six goals and five assists this term, Oxlade-Chamberlain is clearly an important member of the squad at the Emirates, but he needs to be playing first team football regularly to reach the potential he showed for club and country a few years ago.

He spoke earlier in the season about potentially having to consider his future at Arsenal, and you sense that, although he is always around the first team, he doesn’t look like nailing down a starting berth ahead of Theo Walcott, Alex Iwobi, Alexis Sanchez, and Mesut Ozil.

Thus, the 23-year-old should move on this month. He has already been linked with a move to Liverpool, and there’s no doubt that he could do a job for many Premier League teams.

Oxlade-Chamberlain would offer any side pace and directness in the final third, and would inject some creativity into many a front line.
