Ian Maatsen Chelsea return reality clear after Borussia Dortmund loan success

Chelsea are likely to have an eye on tonight's Champions League semi-final between Borussia Dortmund and Paris Saint-Germain.

Tuesday night sees the Parc des Princes host the second leg between PSG and Dortmund in the Champions League. Dortmund hold a 1-0 lead from the first leg thanks to a goal from Niclas Fullkrug at the Signal Iduna Park a week ago.

One player who has been vital to Dortmund's success in Europe this season is Ian Maatsen. The left-back left Chelsea in the January transfer window to join Dortmund on loan after making 15 appearances across the first half of the season.

Since then, Maatsen has made 19 appearances for Dortmund across the Bundesliga and Champions League and has been the starting left-back for Edin Terzic's team. It remains to be seen what will happen with Maatsen's future when he returns to Chelsea this summer after what has been a successful loan spell so far for the defender.
