"He (Rashford) has still played a lot of football, although maybe not the continuous starts, and I'm really pleased for him that he leaves England full of confidence".
Gareth Southgate has expressed frustration about Phil Foden's lack of first-team involvement for Manchester City and warned England's senior players they can not expect to keep their places if they are not involved more regularly for their club sides.
"They have a hard job to do and they have big squads at the top six, with huge competition for places".
Southgate, however, has reassured supporters that the young attacker, who scored the only goal of the game as England beat Switzerland 1-0 on Tuesday, is rated by his club boss as much as anyone else.
"One of the biggest concerns is playing time for English players - that is shown by a number of the squad who came with us in Russian Federation not getting opportunities", Southgate said in a press conference last month.
"For me, it's the biggest club in the world, and I think he's got the potential to be one of the best".
And Rashford has been told that he must leave United in order to be considered as a first-choice striker for England.
"His confidence will be boosted I'm sure, with two goals against top-quality opposition". "He's got huge competition for places at his club, so you can understand [his frustration]". "José [Mourinho] thinks the world of Marcus - he's a huge admirer of him - but he has his job to do".
He now returns to Old Trafford to begin a three-game suspension for a red card picked up 10 minutes after going on as a sub in their win at Burnley in the last game before this worldwide break.
"It's not my business to interfere with club managers". Last season, he played poorly against Brighton, Mourinho had a pop at him and Lukaku went straight back in the next game.
"He is (a special talent)", the England manager said, as quoted by FourFourTwo.
That means he'll miss the next three domestic games for United, matches against Watford and Wolves in the league as well as the League Cup Third Round s Derby County.
