On the day Manchester City spent more than 50 million pounds ($77 million) on another attacking player, its cross-town rival again showed a lack of cutting edge up front to turn dominance and good build-up play into goals. With Europe's summer transfer window closing in England on Tuesday, United has two days to resolve its goalkeeper situation and decide whether to sign a new striker to help out Wayne Rooney, who is yet to score in the Premier League since April. The opening goal arrived when left back Luke Shaw's cross squirmed through to the back post where Mata beat Ashley Williams to the ball and sidefooted a rising shot high into the net. First he met Gylfi Sigurdsson's cross with a downward header inside the near post in the 61st, then supplied Gomis with a brilliant outside-of-the-foot pass.
