#2 More quality attacking teammates
At Chelsea he had some good teammates and settling into new surroundings, there will be more of the same for Morata to enjoy. It was never a case of him lacking service in west London, but a glaring tendency to miss big chances when presented to him meant patience quickly wore thin at Chelsea.
It links back to the pressure that comes with being the Blues' focal point in attack, their main goalscorer who is relied upon to finish chances with ruthless efficiency. Other than a goal glut in the first month of the 17/18 campaign, he scored less and individual performances were also on the wean - missing more and struggling became more evident as time continued.
Antoine Griezmann is easily one of the world's best players and the combinations are endless between the pair - playing alongside him in a 4-4-2, or as part of a 4-3-3 formation, they could link-up well together and already displayed flashes against Betis.
Koke and Saúl Niguez - both struggling with muscular injuries - usually control the midfield, boast an excellent passing range while providing balance between attack and defence. While winger Thomas Lemar hasn't settled quickly from Monaco, there are no questions over his ability Thomas Partey and summer acquisition Rodri are improving all the time in the midfield.
Further forward, both Vitolo and Angel Correa are inconsistent, Gelson Martins joined Monaco on-loan last month and centre-forward Nikola Kalinić is patchy at best. Morata has a golden opportunity to assert himself in Diego Costa's (foot surgery) absence.
He needs a run of consistent displays, where he doesn't necessarily always score but is actually playing well. Atletico's fanbase are largely unconvinced by his arrival - after all he played for their crosstown rivals - so starting positively will do wonders for his confidence. It's difficult to remember the last Chelsea game where he impressed in recent months, because of the indecision and negative body language he so often showed in the final third.
