Chelsea shelled out more than £70million yesterday to secure two marquee signings as Carlo Ancelotti looks to get his men back in the title race and stay on course for European glory in the Champions League.

Wenger, who made no major transfer moves in January, feels it is a signal of intent from the Blues' Russian benefactor.

The Arsenal manager said: "For a while, Abramovich was a bit in no man's land where nobody could really guess whether he wanted to still invest or not. Certainly, that has changed.

"He has decided to put big money in again, and that tells you that certainly in the summer more will come. He is back to full investment.

"If you don't invest for a while, it looks as if maybe he is not as involved in it any more, doesn't like it as much - but when you invest £75m it means more will come.

"It looks Chelsea are back on the market, which they were not for a while."

Chelsea's spending, and that of rivals Manchester City, comes despite the forthcoming UEFA Financial Fair Play Rules, and also came on the day the Stamford Bridge club announced significant losses again.

Wenger continued: "Chelsea supported the financial fair play. In the morning they announce a £70m loss and in the afternoon buy £75m worth of players. Where's the logic in that? It is very difficult to guess.

"Officially they vote for the financial fair play, so they can explain much better than I why they do that."
