Ben Arfa warned at the start of the year he may have to consider his options if the club did not meet his own lofty expectations.
But he now says: "I'm very happy now because they are very good players. They will help our team.
"We have a stronger team than we had before January.
"It's good because last season we did very well and finished fifth but the squad wasn't very big.
"Now, with the players coming in, it is even stronger and we can do something similar again. The squad is better than it was."
