Let me start by saying the January transfer window is a farce. Nothing happens for weeks and then you get a mad rush of deals in the last few hours. Just look at the percentage of deals being done at the final hour.
Why do we need a month? The window should be a week long or perhaps even three-to-five days. It would benefit everybody involved.
With that said, here's my assessment of the business done by the big Premier League teams.
I'm a bit surprised they stopped at Juan Mata. He's a very good signing, but that's a lot of money for a player who was out of favour at his club. He'll improve them and he'll give a lift to the players and the fans, but United needed further reinforcement and to get rid of a few more players.
I'd give them an outside chance of breaking into the top four, no better than that. With Mata's signing—and Wayne Rooney and Robin van Persie back—they have a shot at it, but more arrivals are needed in the summer.
Whether Liverpool sign Yevhen Konoplyanka in this window or not (looks like they didn't, report from Metro here—Ed), I can't see him having a big impact this season. When a player comes in from Russia or the Ukraine they need a lot of time to settle. Should the deal go through, we won't see his best until next season.
The way they've been playing, there was no great need for City to do anything in this window. Sometimes bringing in new players can unsettle your squad and disrupt your rhythm—with new arrivals meaning current players get sat on the bench.
City are doing the right thing. They have plenty of cover at the back and should be well set for the business end of the season.
Loan signing Kim Kallstrom has been around for a while and has a very good left foot.
My worry is that with Theo Walcott and Aaron Ramsey out, Arsenal do not have enough pace going forward. It will become harder and harder as the season goes on—especially away from home, where you need that speed on the break.
It's my prediction that, within four or five weeks, the Gunners will be completely out of the title race. They have tough fixtures coming up and I think they'll fall away.
Mohamed Salah has been dubbed the 'Egyptian Messi' and for the price Chelsea paid—£11 million according to the Daily Mail—he looks a very promising player.
Chelsea have no shortage of attacking talent, but I think he could make a difference for them.
