Depay 12 goals and 8 assists in the dutch Competition at PSV (a team that even had a more horrible season than us, not functioning at all). He is dutch, highly rated by LVG (they will work brilliantly together, communction with RVP and other players will also be beter, he already speaks english whereas with yeheven I seriously doubt that and communiction could be a problem). A player, that excelled this year in a team where it was very difficult to excell in (with beter players around him and a beter coach he could make serious progress). Most importantly he is 20 years old, hasn't reached his top yet, 5 years left of development time (compared to Yehven) this guy I think it is fair to say has the looking of a potential wordclass winger like Robben. A little bit of patience and alot of good guidance and opportunities and he could develop into a fantastic player, couldn't think of a beter coach than LVG to accomplish it aswell.
Rather we spend that £15m on bringing in Depay than on waisting it on a mediocre player that is destined for failure like Yeheven, let him go to Liverpool and let him fail right there, build a wordlcass player ourselves with Depay and together with Januzaj watch us having 2 worldbeaters on the flanks within a couple of years.
