Grzegorz Krychowiak has accused Unai Emery, the Paris Saint-Germain coach, of not telling him the truth about the reasons for leaving him out of the team for so much of last season, and revealed the extent to which their relationship broke down by saying he “felt deception” whenever he spoke to the Spaniard.

Krychowiak followed Emery to PSG in July last year for €30m after spending the previous two seasons playing under him at Sevilla, where they won the Europa League in 2015 and 2016. Krychowiak said at the time of his transfer that Emery’s appointment at PSG was a factor in his decision but the Poland international started only 11 matches in all competitions for the French club and was told in the summer he should look for a new team, only 12 months after signing a five-year contract.

With Krychowiak marginalised to the point that he was not involved in any pre‑season friendlies for PSG, West Bromwich Albion saw an unlikely window of opportunity and signed the midfielder at the end of August on a season-long loan deal that was regarded as a huge coup.

Krychowiak has settled quickly at The Hawthorns and is enjoying English football, yet he is clearly frustrated with the way things unravelled for him at PSG, in particular Emery’s responses whenever he sought an explanation. “I spoke with the coach but every time when I spoke with him I felt deception,” Krychowiak said.

Asked to elaborate on that and whether he felt he was not being told the truth during their conversations about his lack of match action, Krychowiak said: “Yes, exactly. So for me I didn’t understand why. The coach knows me very well. We spent two years together and before I signed the contract he told me to come to PSG, and I didn’t play.”

Krychowiak is open to all possibilities at the end of this season and has not ruled out returning to PSG, although that prospect appears highly unlikely in the circumstances. His move to Albion came out of the blue – he found out about the opportunity of playing in England 48 hours before he signed – and the 27-year-old is honest enough to admit he knew “not a lot” about the Midlands club before signing. Playing in the Premier League was part of the attraction, according to Krychowiak, as was the need to hold down a regular first-team place before next summer’s World Cup finals.

“It was one of the reasons,” Krychowiak said, when asked about Russia 2018 being a factor. “If I want to play for Poland, I need to play and find a club. I didn’t go for the two last games with Poland [in September’s qualifiers]. I spoke with the coach, he told me that it would be better that I find a club, then I will be back [in the squad]. So it was very important for me to have the opportunity to play in the World Cup.”

A keen traveller, Krychowiak spent the summer trekking across the US as well as visiting Mexico and Cuba, and he has already taken in a few diverse attractions in England, including visiting Blenheim Palace, Legoland and the historic colleges that make up Oxford University. “Football players have a lot of opportunity to change the club, the city, the country, to know a new culture,” Krychowiak said. “It’s very nice to discover these kind of places.”
