The 21-year-old, who has been part of Brentford B since the summer of 2019, departs having been a key player for the B Team since his arrival. In total, Nathan turned out 45 times for the side in goal and he also won the Mary Halder Award for his performances during the 2019/20 season.Nathan arrived with the young Bees after coming through the ranks at Swansea City. The Wales Under-21 international will now take the next step in his career with Dundalk, who get their season under way next month. The side finished sixth in the league table last season and get their new campaign under way on 18 February when they host Derry City FC.Discussing Nathan’s departure, Brentford B Head Coach Neil MacFarlane said: “Nathan leaves with all of our best wishes. From the day that he came into the Club he has been the captain of the B Team because he is a real leader both on and off the pitch. He has great standards, drives training every day, and has put in some exceptional performances during his time here.“To see him develop with us on the pitch as well as off it as a human being has been great, he’s an amazing person who will be going to a team who have been involved in European football. It will be a really good challenge for him as he continues to push on with his career.“Not all of the players are able to get through to the First Team but Nathan has been able to benefit from many opportunities to train alongside them, and we know that Thomas (Frank) and the rest of the staff think highly of him because he is such a well-rounded individual and we hope he can go on to have a very good career.”
