The Welsh international has made the move to Glasgow to the Premier League.
The Welsh international moved to Sunderland for a fee reported by the BBC to be in the region of £2 million.
Now the 23-year-old has spoken to the official Sunderland website about the move, in particular about how he hopes the Sunderland fans will live up to what he is sued to from the Celtic faithful.
“It’s been very exciting. It happened really quickly which has been a bit of a shock. Playing in the Barclays Premier League and in front of great fans and in a big stadium is something I’m looking forward to.
“Obviously, at Celtic I played in front of massive crowds and I’m sure they’ll be just as good if not better here so I’m really looking forward to it.”
Of course the Celtic fans are a big act to follow. Often regarded across Europe for their boisterousness in European competition, Matthews is expecting a lot from the Sunderland faithful if that is what he expects going forward.
How needed was Matthews?
Desperately. Sunderland are in dire need of refreshing their defence and with Matthews arrival, along with Sebastian Coates’, they are beginning to do just that.
The Welshman also adds a little bit of pace to the side. In recent times Sunderland have looked sluggish at the back and the former Cardiff City man should help solve that problem.
Will Celtic miss him?
Celtic meanwhile have plenty of cover at right-back. Mikael Lustig is fit again, Saidy Janko has just arrived and Darnell Fisher looks a promising prospect. With newbie Dedryck Boyata also comfortable in the position and Matthews hoping to force his way into the Welsh national set-up again, this represents a good piece of business from all parties.
