- Guerreiro returns to first-team training.
- Portugal international had been out of action since November.
- Hailed as one of BVB's "problem-solvers".
The UEFA EURO 2016 winner suffered no adverse reaction during or after a 60-minute training session on Sunday having recovered from the muscular problems that had sidelined him since November, limiting him to just eight Hinrunde appearances.
Those eight outings were enough for the summer signing from FC Lorient to develop into one of BVB's most important players: Guerreiro scored twice and created two further goals playing between left-back, defensive midfield and attacking midfield.
The Portugal international also scored once and set up a further two goals in three UEFA Champions League appearances as the Westphalian outfit topped Group F ahead of European champions Real Madrid C.F.
Dortmund coach Thomas Tuchel has hailed Guerreiro as one of his side’s "problem-solvers", to which Guerreiro responded on Sunday by saying: "It's always nice when the coach speaks positively about me. You feel a bit of an outsider when you're injured and you have to come in and train at different times."
