The 18-year-old only made his debut for the club on Thursday, scoring twice on that occasion too against Midtjylland.Ander Herrera added to Rashfords two first half goals to ensure goals from Danny Welbeck and Mesut Ozil for Arsenal were in vain. Its unbelievable when you are 18 years old and you come in, Van Gaal told Sky Sports. I can understand it like last Thursday against Midtjylland because you are coming in and you do your thing without any pressure. Marcus Rashfords fairytale continued as he scored twice on his Premier League debut to help Manchester United to a 3-2 win over Arsenal at Old Trafford. But the second time is more difficult and he played a very good match. The things I asked of him, he scores again - four goals in two matches - that is an average that is unusual!You get a chance and you have to perform, you have to do the things that we are asking. I have always said it is not a matter of age, it is a matter of quality and he shows it. Rashford delighted Young striker thrilled with double against Arsenal Asked in his press where Rashfords debut ranked, the former Barcelona, Bayern Munich and Ajax boss placed the teenager in an elite group.I can imagine a lot of them, he said. Patrick Kluivert makes the winning goal (for Ajax) in the Super Cup in the Netherlands. Xavi, fantastic against I think Valladolid (for Barcelona) and also Thomas Muller a fantastic debut. Marcus Rashford grabbed two goals and an assist on his Premier League debut Van Gaal was delighted with the performance of a side missing a number of key players and including several youngsters aside from Rashford.When you see the circumstances, the many injuries and a lot of youngsters are participating, it was a great match, he added. Rashford (left) celebrates with Juan Mata after opening the scoring Also for the fans, they were very enthusiastic throughout the game. We scored goals, we are defending our result and we did it much better than the last matches because we didnt give many chances away.The second half I changed the shape a little bit because I wanted to defend the result. We were more compact in the second half and you can score also so Im very happy because its an important victory over Arsenal - who in my opinion are one of the best teams in the Premier League. Watch Louis van Gaal remonstrate with the fourth official, a confrontation that ends up with the United manager lying flat on his back The key factor is always that you dare to play and we can play very good but we have to move the ball more quickly and we have to switch the game more frequently. The two goals that we scored in the first half were through the switching of the game.That we have improved because we did it, in this game in any case, but we have to do it more I think. Thats the key I think and also that we are defending like a team. Also See: Rashford double downs Arsenal As it happened Man Utd fixtures Get a £10 free bet! New Orleans Saints Shirts .

NEW YORK -- Second baseman Neil Walker has accepted a $17.2 million qualifying offer and will return to the New York Mets for 2017.Walker confirmed via Twitter that he will be back with the Mets. Happy to say Im back in Orange and Blue for 2017!! Lets go Mets! #unfinishedbusiness, Walker posted on Monday.?Walker underwent season-ending surgery to repair a herniated disk on Sept. 8. That likely depressed his ability to get a multiyear contract, even though his lower-back woes are expected to be behind him.Absent the back surgery, Walker might have been able to land a deal between what Daniel Murphy received with the Nationals (three years, $37.5M) and Ben Zobrist received with the Cubs (four years, $56M) last offseason.Walker, 31, hit .282 with 23 homers and 55 RBIs in 412 at-bats with the Mets in 2016. The long ball total matched his career high and trailed only that of St. Louis Jedd Gyorko (30) and Murphy (25) among National League second basemen.Walkers return for the 2017 season raises the Mets payroll commitment, including estimates for arbitration-eligible players, to roughly $124 million. It has a direct impact on Jose Reyes, who might recede to a backup role with, potentially, some outfield time, assuming starting infielders David Wright, Asdrubal Cabrera, Walker and Lucas Duda?are all healthy.A Pittsburgh native, Walker was selected by his hhometown club in the first round of the 2004 draft.dddddddddddd He remained with the Pirates until he was traded to the Mets last December for left-hander Jonathon Niese.Despite the lack of a long-term attachment to the Mets, Walker demonstrated his affinity for the team by maintaining a presence in the clubhouse this past season, even after undergoing back surgery with nearly a month remaining in the season. His wife gave birth to the couples first child, daughter Nora Vail, in late August.Outfielder Yoenis Cespedes will decline his qualifying offer. After he vacated the remaining two years and $47.5 million on his previous contract by opting out, returning for one season at $17.2 million wouldnt have made sense. The Mets will recoup a draft pick if Cespedes signs elsewhere, though there is still a chance he returns.Eight other free agents did not accept offers from their former teams by Mondays 5 p.m. EST deadline: outfielders Jose Bautista (Toronto), Ian Desmond (Texas), Dexter Fowler (Chicago Cubs) and Mark Trumbo (Baltimore), designated hitter Edwin Encarnacion (Toronto), closer Kenley Jansen (Los Angeles Dodgers) and third baseman Justin Turner (Dodgers).Information from the Associated Press was used in this report.
