In his column for the Mail on Sunday, Lineker wrote: "I would not have thought Robbie Keane enjoyed his Saturday night too much after Tottenham's 3-0 trouncing at the Emirates Stadium.
"As the Spurs captain, I'm sure Keane had the club's best intentions at heart when he said before the game that their squad had greater strength in depth than Arsenal's.
"Arsenal would have been fired up for the game anyway but by making such a provocative statement, Keane probably put unnecessary pressure on himself. Leading his team out in the tunnel, he might have felt a need, even subconsciously, to try to justify his bold comments.
"When things started to go wrong, his mind would have flicked back to what he had said. On yesterday's evidence, the truth is that Keane was premature in comparing the two clubs."
