Jens Lehmann: Arsenal must win Premier League under Unai Emery

Emery has already brought in the likes of Lucas Torreira, Sokratis and Bernd Leno.

Uruguay global Lucas Torreira has arrived in a £26m deal from Sampdoria to add more steel to the Arsenal midfield, while Lorient teenager Mateo Guendouzi has completed a switch.

Arsenal fans will be hoping he can get off to a good start when his side host Manchester City on Sunday.

Arsenal's Emery will need to reverse a terrible recent record for the club against City, however, if the new era in north London is not to start in disappointing fashion.

The 21-year-old was restricted to just a handful of starts after being hampered by a serious hamstring injury for much of last season and his place in Ernesto Valverde's first team this season is under threat following the arrival of Malcom from AS Roma.

"We conceded a ridiculous number of goals around 50 or something which Arsenal hadn't done in maybe 15 years so one thing he's been working on unsurprisingly is making the team a bit more solid and better organised in that area".

"It remains to be seen how successful that is but that's an area he's focused on".

"In the past, Arsenal have won games on great football, individual brilliance and having great attacking players", Carragher told Sky Sports. The preseason has also been a success for Arsenal, who have not registered a single 90-minute defeat during their summer preparations (W3 D2), with forwards Pierre-Emerick Aubameyang and Alexandre Lacazette netting four goals each during that stretch.

The Gunners appointed the Spanish head coach as their new manager at the end of the 2017-18 Premier League season following a hard campaign.

He also suggested that his former side, under Emery, will mount a title challenge this term.

"Like Arsene [Wenger], he's a workaholic: he's always watching film of training or the opposition. It's been great getting to know him".
