It's been a very good window and getting a quality defensive midfielder in would have made it an excellent one.
Doesn't look like it is going to happen now and who knows, maybe the right player wasn't available at this time. Maybe they think that Luiz and the soon returning Nakamba can cover it until the right player becomes available in the summer.
The Targett move surprises me if we don't bring any cover in. Then again, maybe they view Young as adequate cover until the summer and again more options are available.
Will be interested to see how Bentacur looks at Spurs.
