So far during Unai Emery’s first transfer window in charge at Arsenal football club the focus has primarily been on incoming transfers.

Stephan Lichtsteiner, Sokratis Papastathopulos, Bernd Leno, Lucas Torreira and Matteo Guendouzi have all become Gunners since the transfer window opened, and with Emery keen to continue adding players to his new-look team, plentiful exits from the current squad look likely.

Jack Wilshire was the first player to make the move when he transferred to West Ham United last week, but who will be joining him in leaving London Colney?

Goal.com are reporting that Emery is open to hearing offers for several first team players – namely Nacho Monreal, Shkrodan Mustafi, Danny Welbeck, Petr Cech, David Ospina, Carl Jenkinson and Lucas Perez.

This list of names doesn’t come as an enormous surprise with the possible exception of Nacho Monreal, who was a fan favourite last season. The Spanish defender is now 33 years old and is beginning to look like he will not have a part to play in Emery’s plans for the future at the club.

Real Sociedad are reportedly interested in securing the left-backs services and the player himself may be open to a return to his native country.

Petr Cech and Shkrodan Mustafi may also be surprised to see their names on this list. With Leno and Sokratis coming into the team, there positions may be in jeopardy, especially considering they did themselves no major favours in keeping themselves in contention last season.

There are some other names on the list that don’t really come as a surprise at all, perhaps most so Carl Jenkinson and Lucas Perez. The two players have not been part of the team for several months and would have to impress their new manager in a big way during the ongoing pre-season to put themselves in contention to remain at the club.

After a fine World Cup showing for Columbia, David Ospina may feel a little aggrieved by his inclusion, but like Cech, with leno joining, it appears the number 1 choice at the club has been sewn up. With both Ospina and Cech both having a lot left to give, they may be eager to have a regular starting place and could be open to a transfer.

Danny Welbeck may have made it to a World Cup Semi-Final with England, but his time at Arsenal may very well have reached its climax. The striker has been riddled with injuries since arriving from Manchester United in 2014 and generally has been unable to win over his critics during his time in North London.

With Arsenal’s attacking options perhaps it’s strongest outlet (when fully fit), maybe it would make sense for Welbeck to seek new pastures – especially considering the forward can cause a lot of problems when he is in good shape.

Emery has pledged to integrate youth players already at the club as they gain experience from playing alongside older players. This, with the promise of more additions, means there will be a lot of chopping and changing over the next 3 weeks.

Arsenal reportedly entered the window with a £70 million transfer kitty – with 5 signings already completed, and more on the way, there will need to be additional exits.

So, what positions does Emery need to free up money so he can add to? Well, if Monreal is to depart it would mean he would need to continue his reformation of the defence by bringing in a new defender to occupy the left full-back position.

With strong forward options available it Mesut Ozil, Henrikh Mkhitaryan, Alexandre Lacazette and Pierre-Emerick Aubameyang, the one position that is badly needed to be filled is that of a winger.

Ever since Theo Walcott was sold to Everton Arsenal have been lacking an out-and-out winger, so this is something Emery will look to rectify in the coming weeks with Aleksander Golovin and Kingsley Coman linked.

Both of these players – and likely any other target that would emerge - would require significant transfer fees, so more exits will definitely be necessary.

With the transfer window closing for English top-flight clubs on August 9th – the day before the first match of the season – Emery will have a lot of work to do in addition to the pre-season trips to Singapore, Ireland and Sweden.

After Emery began his tenure with a comfortable 8-0 win over Boreham Wood in an exhibition game, he will be looking to continue becoming acclimatised to his new team when they jet off to Singapore on July 22nd to face up against Atletico Madrid on July 26th and his former club Paris Saint Germain on July 28th.

When the first game of the new Premier League season against Manchester City rolls around on August 12th, you can expect a significantly different squad from the end of Arsene Wenger’s time at the club.
