Perez (AZ) scores from the penalty spot.
Lastuvka guesses correctly and dives to his right but he is never going to reach Perez's superbly struck penalty.

Ramzi (in) - Sektioui (out) (AZ)
Not the most attacking double substitution Adriaansee could have made, adding a defender for a winger.

Huysegems (in) - Nelisse (out) (AZ)
Like for like as Adriaansee gives his hard-working lone striker a well deserved rest.

Mathijsen (AZ) scores!
The centre-back, a goalscorer in the last round against Aachen, regains the lead for the home side after more slack marking from Shakhtar. Sektioui creates space on the left flank and crosses to the near post where an unmarked Mathijsen heads past Laštuvka at the near post.

Tymoshchuk (Shakhtar Donetsk) is cautioned by the referee.
The Shakhtar captain is penalised for pulling Nelisse back and the yellow card means he will be suspended for the second half at the Alkmaarderhout.

The second half begins.

The referee blows for half-time.

Matuzalém (Shakhtar Donetsk) scores!
The Brazilian midfield player has had a quiet game, but draws the sides level right on half-time after Alkmaar fail to deal with a Ravzan Rat cross. The ball falls for Aghahowa, who holds off two defenders before squeezing the ball to Matuzalem and the 24-year-old scuffs a shot into the bottom right-hand corner.

Elano (in) - João Batista (out) (Shakhtar Donetsk)
Joao Batista does not appear to have anything wrong with him as he jogs off and the change appears tactical as Lucescu decides to risk his €7.6m signing from Santos FC.

Nelisse (AZ) scores!
The 26-year-old opens the scoring for Alkmaar with an excellent finish that gives Lastuvka no chance. Kenneth Perez delivers a corner to the near post and under pressure from Lewandowski, Nelisse flicks the ball into the back of the net.

De Cler (AZ) is cautioned by the referee.
The 26-year-old is penalised for a late challenge on João Batista as the Brazilian playmaker attempted to break free.

The match is under way.
