Cahill finally completes £7m switch to Chelsea

The England centre-back Gary Cahill completed his move from Bolton to Chelsea yesterday. The 26-year-old joins for a fee of £7m after two weeks of negotiation over personal terms. Cahill, who would have been out of contract at the end of the season, was thrilled to have joined Andre Villas-Boas's side, who lie fourth in the Premier League. "Chelsea is a massive club, it is a club that looks to win trophies season-in season-out and it is a big opportunity for me to be a part of that," he said yesterday. "Opportunities like this you can't turn down."
