If Ronaldo should be given more chances to play in every game like last season I'm very sure he will score more goals. The game Manchester United played against arsenal in the EPL Ronaldo was brought into the field in late hours of the game, even if he did not score goals in that game but performed very well. I really understand why Ronaldo haven't scored more goals this season, he never had the privilege to have good time in all the games.
Last goals scoring by Cristiano Ronaldo trough penalty kick when Manchester United won at away match against with Sheriff, I think if have more chance in starting eleven will see many goals scoring by Ronaldo in Europe League. No doubt when Manchester United played on Europe League dominance by second composition player and little difficult for Ronaldo get service and assist, but seems not reason because know how fight games play from Cristiano Ronaldo and always make attempt for him scoring goals on every chance he has with Manchester United.
Seem on next Europe League match easy for Manchester United to win against Omonia and have chance again for Ronaldo can scoring goals, but I think he will settle in starting eleven in Europe League because after facing difficult get regular position in domestic league, Erik Tan Hag will settle regular position for Ronaldo in Europe League.
