The 26-year-old has been criticised for his actions in the lead up to Gabriel Paulista’s red card during the game, which the Blues went on to win 2-0. The Spain international had pushed and hit Laurent Koscielny earlier in the match, winding up the former Villarreal man.
“Diego Costa may be the world’s grumpiest, most annoying striker, but you would always choose to play with him rather than against him,” said Lineker.
“He’s a real street fighter, and let’s not forget that he’s also a proven goalscorer.”
Costa has become known for these kind of incidents, which have come to mar a fine goalscoring record for the Stamford Bridge outfit. Last season, the forward managed 21 goals in 37 appearances in all competitions, although this time round he has only hit the back of the net twice in six matches so far.
The striker’s efforts on Saturday may be what Chelsea have needed to kick start their campaign. Having managed only one win in their first five matches, the Blues were in desperate need of a result against the Gunners. With the first half sending off of Gabriel playing a key part, they are now all set to charge back up the table.
