Having been linked with the Barcelona forward for much of the summer, a deal was finally completed on Tuesday.
A loan switch had been mooted, but Bojan has moved to the Britannia Stadium on a four-year contract for an undisclosed fee.
His capture is considered to be quite a coup, given that he has also turned out for Roma, AC Milan and Ajax and has been capped at senior level by Spain.
Muniesa, who made a similar switch last summer as he swapped Catalunya for Stoke, is delighted to be welcoming a familiar face and is backing Bojan to be a big hit in the Premier League.
He said in The Sentinel: “I have spoken with him. I said that everything is okay here – team-mates, training and football.
“Also, to play in the Premier League will help him grow as a player and is a nice experience. He will enjoy it. I will help him with everything.”
Muniesa added: “He is a very good striker, but always playing as the second striker.
“He can also play right winger, but I think his best position is second striker because then he is in the area and he has a very good finish. He is also quick with a good touch.”
