Former Manchester United and Arsenal forward Alexis Sanchez scored twice as Italian champions Inter Milan thrashed Sampdoria.

In their first match since being confirmed as the winners of Serie A for the first time in 11 years, Inter were 3-1 up at half-time.

Roberto Gagliardini opened the scoring for Antonio Contes side before Sanchez scored two in the space of 10 minutes.

Andrea Pinamonti added a fourth before Lautaro Martinezs penalty.

Sampdoria, whose goal came from Senegal winger Keita Balde, are ninth in the table with three matches remaining.

Inter are 15 points clear of second-placed Napoli, who won 4-1 away to Spezia earlier on Saturday.
