Everton boss Dave Moyes is delighted to have Thomas Gravesen back on Merseyside.
"He is a bubbly lad and his character is strange, to say the least," said Moyes. "But it's good to have him back in business as we are in an important period. He's got a winning mentality and good experience and he can give us something different in midfield.
"The problem with Tommy is that he came here desperately in need of match practice and he then played for 29 minutes at Bolton when he first arrived. The idea was to get him a little bit more ready for the Premier League.
"But he's hardly played since then. He's had no real match practice and he might be in a worse position because of that than when he came from Celtic.
"He's been out injured for month. He can make impacts in games, though. We want to get him back ready so that he can start games."
