The Gunners have finally closed two transfers this summer, but there's a catch about one of them.

Arsenal may not have too much money to spend, but they surely recognize an investment opportunity when they see one.

Coach Unai Emery had promised that the team would make noise in the summer transfer window by unveiling "one or two players". Today, Emery showed that he is a man of his word, as the Gunners have unveiled Dani Ceballos and William Saliba on social media.

The Spanish midfielder earned praise from European journalists following his impressive performance in the U-21 European championship. He will join the Gunners on a one-year loan deal. Speaking about this transfer, Ceballos admitted the main reason why he chose to embark on this adventure with the EPL side.

But the good news did not stop for Arsenal fans, as highly-rated center back William Saliba will also join the Gunners on a long-term deal. The footballer even shared how Matteo Guendouzi urged him to sign with the Gunners.

The French defender will not join Arsenal until next season, as one clause of the deal demanded the footballer to stay at Saint-Etienne for the 2019-20 season.

Arsenal is still keen on luring some talent to the Emirates, with Lucas Vázquez and Kieran Tierney named as options to sign with the Gunners.
