yep, arsenal have been winning games because of scoring late. but in a lot of games this year we've been up against teams sitting way behind the ball, and in those situations often its working and working to break them down and it becomes easier when they are a little tired and mistakes get made.
as for babel, i wouldn't think that benitez tells babel to shoot like mad, but when you come from playing a lot of games, a team pays, was it 13ish mil, for you and you've barely been given a chance. in a game you are completely dominating, against a side thats playing so pitifully its a joke he's going to want to grab a goal or two to try to convince his boss he should be starting. but as soon as he came on, he was running around players(abeit not very good ones), shooting coming extremely close, was involved in the 3rd goal i think, didn't he pass it off between him and gerrard who crossed it for the finish?
liverpool's main problem is buying a lot of players, but often ignoring those very very very top quality players, instead buying slightly less good players, but more of them with the idea of having an incredibly deep squad. which they might well have, but they lack as good a first team as they should have. but a not perfect side on a great day will play great, its just on a poor/average day i think theres a lot of teams who can beat them if the other side is having a great game.
but chelsea and liverpool have had the problem of, too many established first team players being brought into the squad, which creates issues of players going from first team to barely playing, doesn't always work out so well.
benitez's press conference where he was constantly repeating the thing his owners had told him, it was so funny. though it sounds like the owners said they'd talk about january when they were back in the uk mid december, so he's being a bit of a baby about it. at some point owners lose faith with " i just need 3 more players and we can win the league", reply " but you've said that for 3 years now" .
