Arsenal’s quest for a 21st successive top four finish in the Premier League took another severe dent on Saturday as they meekly lost 3-1 at West Brom.

Arsene Wenger’s men had the chance to get right into the mix for a Champions League spot being the first game of the weekend, but a brace of headers from Craig Dawson and a Hal Robson-Kanu strike secured Tony Pulis’ men a deserved victory over the Gunners, who in turn suffered a fourth defeat in five league games.

Once again, Wenger’s future as manager has been subject to much debate in the aftermath, while they also saw themselves slip a place in the league table after Manchester United beat Middlesbrough 3-1 on Sunday to replace them in fifth.

It means that Arsenal are six points adrift of Liverpool in fourth, albeit do have two games in hand on Jurgen Klopp’s men, and although they still have that and an FA Cup title to play for, it hasn’t stopped speculation increasing about potential incomings and outgoings at the Emirates this summer.

It still remains uncertain whether or not Mesut Ozil and Alexis Sanchez are at the club come August, while the futures of midfielder Alex Oxlade-Chamberlain and Santi Cazorla are also not yet resolved.

However, they have also been linked to several quality players, so here is what Arsenal’s unstoppable FRONT FOUR could look like after an overhaul at the Emirates this summer…

Theo Walcott

England international Theo Walcott, albeit not included in Gareth Southgate’s squad this week, is embarking on one of his best goal-scoring seasons since moving to Arsenal back in 2006.

The 28-year-old has netted 17 goals in just 30 appearances for the Gunners this term, including eight in the Premier League, and is well on course to beating his best season tally at Arsenal, which came back in 2012/13 when he scored 21 times for Wenger’s side.

Despite his excellent goal-scoring form, Walcott still struggles to affect games when Arsenal need him most, and that will surely be something he looks to put right in the rest of this season, and going into the 2017/18 campaign.

Ross Barkley

There probably wasn’t much interest in Everton’s Ross Barkley back in the autumn, given that his form wasn’t particularly great, but now the 23-year-old is a man in demand.

That’s because since the turn of the year, Barkley has been in great form, scoring once and laying on five assists to help Ronald Koeman’s men six of their nine Premier League games, and move level on points with Arsenal in sixth.

Unsurprisingly, Barkley’s form saw him receive a recall to the England squad for this week’s games against Germany and Lithuania, and it has also seen interest mount for the midfielder, with the likes of Arsenal and Tottenham reportedly interested.

And given that Mesut Ozil may well be on his way out of the Emirates this summer, a move for Barkley should be high on Wenger’s list of priorities.

Kylian Mbappe

Kylian Mbappe’s stunning display in Monaco’s Champions League last 16 victory over Manchester City this month has got the whole of Europe talking about a potential superstar.

The 18-year-old netted in their 5-3 defeat to Pep Guardiola’s side at the Etihad Stadium in the first leg, before getting the opener and paving the way for a Monaco comeback in the second leg, a game they’d end up winning 3-1 and thus progress to the quarter-finals on away goals.

But it has not just been in Europe where Mbappe has shown this term, he has been excellent in the league as well, scoring 12 goals and laying on five assists in just 22 appearances, only half of which have been starts.

And with 11 goals in his last nine games in all competitions, Mbappe has shot to fame, and as a result several top sides are keeping tabs on the starlet, one of which reportedly is Arsenal.

Wenger clearly sees him as the next big thing, so must break the bank to acquire his services this summer.

Alexandre Lacazette

With Alexis Sanchez’s future looking more and more like it’s away from Arsenal, Wenger will have to bring in a player to compensate for the Chilean’s goals, assists, and overall attacking play.

And one man he could turn to is Lyon’s Alexandre Lacazette, who has scored 23 goals in just 24 Ligue 1 matches this season.

The 25-year-old has been one of the most prolific goal-scorers in Europe over the last few years, netting over 20 times in each of the last four seasons in France, totalling 105 goals in 174 games for the French outfit.

That is the sort of record which could give Arsenal a serious boost in their quest to land the Premier League title, and given that the French international reportedly is ready to leave this summer, Wenger must act fast to land the striker in the transfer window.
