Newcastle United has signed French winger Gabriel Obertan on a five-year deal from Premier League champion Manchester United, the north-east club said on its website Tuesday. “His best years are ahead of him which is exactly what we want at this club and with the backing of our magnificent fans I'm sure he will prove an excellent signing for us,” Newcastle manager Alan Pardew said in a statement. Obertan, 22, struggled to make an impact at Old Trafford after joining from French Ligue 1 side Girondins Bordeaux in 2009, making only 15 appearances last season. The former French under-21 international said he was looking forward to playing more regularly at Newcastle. “I spent two good years in Manchester but it was a bit difficult with the competition and I really needed a club where I could play more games,” Obertan said.
