New York Red Bulls have completed the signing of former Lyon and Brazil midfielder Juninho Pernambucano from Vasco da Gama.
The 37-year-old, famous for his ability from free-kicks, will be added to the Major League Soccer team's roster pending receipt of his visa and international clearance.
Red Bulls sporting director Andy Roxburgh told the club's official website: "Juninho is a world-class player who our global sporting director, Gerard Houllier and I have known and admired for many years.
"Aside from being a top dead-ball specialist and a tremendous talent, Juninho is a fantastic professional both on and off the field. He is in great physical shape and we think he can make a positive impact for us in 2013."
Goals from Victor Wanyama and Gary Hooper earned Celtic a 2-0 triumph over St Mirren on Saturday, their first three points on their own turf since a 1-0 victory over Hearts on October 7.
Celtic were also held by Arbroath at home during that spell, when they failed to beat Kilmarnock, Inverness and St Johnstone in the SPL.
Matthews, whose team host Ross County on Saturday, told Celtic TV's Huddle Online: "I think we played better than we normally have done at home this season.
"Teams come here and make it difficult for us and so far we haven't been able to break them down.
"But we showed we could do it against a good team and hopefully we can get a run going at home now.
"We have got a game in hand and if we win that we go seven points clear. That's a healthy gap so hopefully we can get a run going and build that gap."
