He is starting to put in some impressive performances and some telling contributions. So is there more to come?
He is showing why Tottenham battled it out with Liverpool to sign him from Swansea. So far this season he has been a very good goal threat, he has arrived late into the area and given himself a good chance of scoring. You only need to look at the goals he scored against both Norwich and Chelsea.
Likewise you can see the understanding built up between himself and new signing Christian Eriksen, they seem to combine well going forward.
The thing that has caught my eye this season has been his ability to finish so well. To those who have watched more of the Icelandic midfielder will say he has always had that ability.
One of his finishes against Norwich involved opening up his body and was perhaps one of the more glamorous and eye-catching finishes you will see, but the finish against Chelsea shows some persistence with a finish that was incredibly difficult to pull off.
His goal scoring record has been pretty good during his time in the Bundesliga at Hoffenheim, by scoring ten goals in his only season over there is quite an impressive return. On his Premier League return to Swansea he managed to score seven goals when he was arrived in the January transfer window in 2012.
He wasn’t as prolific in his first season at Tottenham as was perhaps expected, or he wanted to be returning seven goals – but this season shows that they have yet to see the best of their midfielder.
