Arsenal completed their transfer window in some style, as they completed the long running transfer saga of Kieran Tierney joining the Gunners – and then managed to get the defender they needed with a late move for Chelsea’s David Luiz.

The two purchases saw a total of six new players acquired this summer, and some real issues addressed in the squad.

The buy of Celtic’s left back Kieran Tierney could be seen by some as a gamble, and there should be some reservations regarding the 23 year old Scottish defender. For a fee of around £25-£27m, it would be expected that the new buy would have the world at his feet and at the very least fully fit, but Tierney is currently on the treatment table – and his injury woes are well documented.

Those that have seen Tierney in action however, can fully understand why Arsenal maintained their quest to sign him. A truly roving wing-back, Tierney has an incredible burst of pace and a great delivery from out wide, and perfectly suits Unai Emery’s preference for width from back to front on the pitch.

Injury worries aside, if he can stay fully fit, then Tierney has what it takes to leap the giant chasm between the Scottish Premiership and the Premier League.

Then there is David Luiz.

The opinion is split as to whether this purchase was the best idea from a Gooner perspective. Luiz has split the camp, but rewind a few weeks back and a healthy percentage would have been happy with the free transfer of Gary Cahill to fill a gap in our defence – and Luiz is a far better option.

Luiz has signed for two years and at 32, we will still be getting an effective defender. Much has been made of his perceived weakness when played in a back four, but with Emery favouring three at the back for large periods of last season, Luiz can be a real lynchpin at the back.

The Brazilian has cost us £8m and is the ideal stop gap until William Saliba returns from his one year return to St Etienne. With Sokratis, Rob Holding and Calum Chambers offering plenty of solid options at the back, we have a defence that seems to be pretty well stocked for a rigorous campaign.#

With Gabriel Martinelli providing a different option for the present and future up top, Dani Ceballos giving us plenty of choice and versatility during his year with us and Nico Pepe providing the goals and danger up top, Raul Sanllehi and co have made every pound of our budget count.

Just in time too. The Premier League is back and we need every player to stand up and be counted.
