Shaqiri - Huge expectations at Bayern, flops, move to a decent Italian team in Inter for a bit before settling in at a relegation candidate in the PL in his mid twenties.
Deulofeu - Huge expectations at Barca, flops, moves to a decent Italian team in Milan for a bit before settling in at a relegation candidate in the PL in his mid twenties.
They're in the same tier ability wise and have had a similar career path so far, but keep convincing yourselves a few good NT performances makes Shaqiri a much better player. Deulofeu would easily get into the Swiss team as well.
Get real, the guy has been at Stoke for three seasons and is 26 now.
